The Wildest Autograph Chase We’ve Ever Done: Completing a Triple Antetokounmpo Card
Some autograph signings go smoothly.
Others turn into full-blown adventures.
This story falls squarely into the second category.
On this episode of The Power Sports Memorabilia Show, I’m sharing one of the most extreme lengths we’ve ever gone to complete a signed item—and it involved chasing down Giannis, Thanasis, and Kostas Antetokounmpo across the National Sports Collectors Convention, through security, and all the way to a hotel breakfast in downtown Chicago.
And yes… it was all for one card.
The Card: A Triple Antetokounmpo Jersey Swap
The item in question was a Panini jersey swap card featuring:
-
Giannis Antetokounmpo
-
Thanasis Antetokounmpo
-
Kostas Antetokounmpo
The goal was simple in theory:
Get all three brothers to sign the same card.
In practice? Not so simple.
Step One: Giannis (Friday Night)
Giannis was signing Friday night ahead of his public appearance, and everything went according to plan… at first.
Except for one thing.
Giannis accidentally signed under the wrong brother’s image—a completely understandable mistake given the jersey swap design.
Luckily:
-
The card was glossy
-
The paint pen signature wiped clean with an alcohol wipe
-
Giannis re-signed in the correct spot
Crisis averted.
Or so we thought.
Saturday Chaos: Missing Thanasis and Kostas
Saturday should have been easy:
-
Thanasis and Kostas weren’t overloaded with items
-
Multi-sign items are usually straightforward backstage
But as the afternoon rolled on, something felt off.
By mid-afternoon:
-
No Thanasis
-
No Kostas
-
No signings happening backstage
Eventually, we learned the worst possible news:
All three brothers were already walking the main show floor with Giannis.
That’s a nightmare scenario.
Why?
-
Massive crowds
-
No way to approach discreetly
-
Zero chance of pulling out unsigned items without looking like autograph hunters
We tried everything:
-
Tracking them across the floor
-
Following with credentials
-
Coordinating with agents and security
Nothing worked.
By the time they reached their vehicle, we were told:
“They’re done signing.”
At that point, we assumed the card would remain Giannis-only.
Sunday Morning Plot Twist
Sunday morning, I arrived early, fully believing the opportunity was gone.
Then came the unexpected twist:
The brothers were still in town—but leaving for their flight shortly.
The catch?
-
They were already at their hotel
-
Their flight was imminent
-
I didn’t even have a car
Through a last-minute scramble, we secured a vehicle, grabbed the items, loaded up pens, and raced 25 minutes into downtown Chicago.
The Final Stop: Hotel Breakfast
I arrived at the hotel just after 9:20 AM.
Security was already staged. Vans were ready.
At this point, it felt exactly like what we never want to be:
An autograph chaser.
But then came another break:
-
Alex Antetokounmpo spotted me
-
He helped coordinate everything
-
Led me to the restaurant where the brothers were eating breakfast
Yes—breakfast.
Signing at the Breakfast Table
The brothers knew I was coming.
We sat down:
-
Completed the triple-signed jersey swap card
-
Finished additional cards
-
Signed a jersey (gold paint pen instead of silver due to a last-second pen mix-up)
All signatures came out clean, bold, and perfectly placed.
Against all odds, the card was finally complete.
Why This Story Matters to Collectors
This wasn’t about hype.
This wasn’t about shortcuts.
This story shows:
-
How unpredictable autograph signings can be
-
Why preparation matters
-
The behind-the-scenes work collectors never see
-
The lengths required to properly complete high-end multi-signed items
Most signings aren’t like this—but when they are, you don’t quit halfway.
Final Thoughts
That triple Antetokounmpo card:
-
Started with a mistake
-
Nearly failed on Saturday
-
Was saved at the last possible moment
It’s now a fully signed, one-of-a-kind piece—and one I’ll never forget.
Sometimes the story behind the autograph is just as valuable as the autograph itself.

The autographs turned out better than I could have imagined. Was a pleasant experience from sending to receiving back the items. You have a customer for life.
Nice big autograph!
Great autograph on this giant 2XL jersey
Power Sports was very helpful. They will answer any questions throughout the process of getting your Autograph. And they packed very well when they ship it back to you.
Another great looking signature added to my team signed helmet. It is great to get notifications throughout the process and using UPS is great to protect my items.
Nice autograph signed by former NY Mets great. Thanks Matt Powers and his team for this signing event.

I’ve been holding on to this hat forever!! Finally got the opportunity to get it signed NBA legend Alex English.. Courtesy of Powers Sports!

Another perfect autograph on my 3000 hit baseball. Always a great experience! Thanks again.
I've had this card since the age of 12. Never had the opportunity until now to get his RC signed. Thanks Matt for making this happen!!
Once again, Matt and his team delivered a smooth, professional experience in obtaining a Dustin Pedroia autograph (with authentication) to a book already containing a number of Red Sox greats’ signatures. I recommend Powers Spirts Memorabilia highly.
Great experience. Card was just as described. Excited to have this added to the collection.

Fernando Tatis Jr 2019 Topps Baseball Rookie Card RC #410 Graded PSA 9 MINT
😍 such a nice autograph! Thank you!
Thank you for another awesome autograph!
Mr. Powers delivered on my request for this Cal Ripken jr. autograph. It was a nice size clean and perfect signature better than I expected. Mr. Powers team is quick to respond with any concerns you may have and keeps you posted on your item. I will absolutely be getting more signatures through them to finish my collection. I highly recommend Powers Sports to anyone that has any doubts. I use to do send ins with Steiner sports until he sold, to me Powers picked up where they left off and I couldnt be happier. Thank you
Great experience as usual! I’ll definitely be getting more autographs in the future!!
As good as it gets
Smooth transaction
The process was smooth and easy as always.
Awesome!
The color match ink auto looks great! Thanks!
A fantastic addition to the set. Bosh's autograph really pops on this one. Thanks!
This might be the only autograph of this card that has his whole auto on it. Great addition to the collection!
The COA wasn't close to where I asked for it to be placed. I'm not sure how this was missed but it was a bummer when I saw that.
This came back amazing! The autograph was very clean! Thanks!
This completes my set of sketch cards. It's been fun doing this.
This was just the COA. Thanks!
It's awesome to get this one back! Another added to the Collection.
Great job by Powers Sports once again! They were able to secure a great signature from Andy Reid on my trading card, using the exact type pen and the exact location that I requested. Accuracy and quality are their top priority!
I submitted 2 cards to get them signed by Patrick Ewing himself. Thanks Matt Powers and his team for this signing event.
