Collect all 20 characters across both Pack 1 and 2 and search for Red and Yellow parallel chase cards.

Collecting just got a lot more peaceful at this year’s San Diego Comic-Con with Upper Deck’s convention exclusive Peacemaker trading card packs! Each pack is fully armed with the entire 10-card base set, plus 1 Canvas Graphics card and 1 Rainbow Foil Board chase parallel!

I've seen a Fantastic Four card by Topps that says "Thanks 4 Visiting" on the back.

Looks like Topps had 4 different Fantastic Four cards at the show, 1 card per day.

There is a 5 card Alex Ross set. I have seen Fantastic Four, Superman, and Spider-Man.

Not sure who cards #1 and 4 are, but the above are # 2, 3, and 5.

Looks like the other 2 cards are Dr. Doom and Krypto (Superman's dog)
