This is a  2025 exclusive San Diego Comic-Con poster for the upcoming movie in December of 2025 for Percy Jackson and the Olympians. It was obtained at San Diego Comic-Con this July. Only attendees with wristbands could acquire a signed poster, so the number signed was quite limited.
 
The poster has been signed by 
Walter Scobell
Leah Sava Jeffries
Aryan Simhadri
Charlie Bushnell
Dior Goodjohn
Daniel Diemer
Timothy Simons
Jon Steinbeferg
Craig Silverstein
Dan Shotz
 
There are a few thumbnail imprints at the very bottom of the poster, but nothing significant. With 10 people handling the poster, it is not surprising. One autograph at the very bottom of the poster has one letter slightly smudged but nothing major as well.
 
You will receive a certificate of authenticity from Tinkerbelltalks.com with a lifetime guarantee on the authenticity of the autographs or a full refund would be made.
