PEE-WEE'S PLAYHOUSE FUN PAK

These packs included cards, stickers, tattoos, and toys featuring images from Pee-Wee Herman's groundbreaking kids' show, as well as original silly art. There's a very comprehensive description and appreciation at The Topps Archives:

"In 1988 Topps came up with one of the most innovative sets they ever produced, right up there with Pak O'Fun and Laugh-In. Pee Wee's Playhouse must have been a risk as the show was mid-run in 1988 but that did not stop the creative team from going bonkers."
