These Variant Cards which can be found in WP Chrome Packs are one of the coolest chase items done for Wacky's in recent years IMO.
There looks to be 9 Titles found so far. The cards are found 1:1500 Packs. The below list is from this board's WP Chrome Master list:
Altered Art: Campy w/ Ugly Button, Kook-Aid w/ Make Your Own Name, Demented w/ Ugly Sticker, Cap'n Crud w/ Mars Attacks.
Mixed-Up Character: Koduck w/ Quacker, Quacker w/ Koduck, Commie w/ Ajerx, Ajerx w/ Gadzooka, Gadzooka w/ Minute Lice.
The fact that these cards pay homage to Norm Saunders exclusively is a very nice move by Topps. To see Norm's art redeployed on different Wacky titles and to see his art from other releases show up on Wacky's is so special.
My sense is that many of these cards are sitting in kids collections with the owner having no idea of the rarity of the card in his or her collection.
Please post what you have from this special group of cards.
