Here's an example of the kind of stuff that's on the back of my new Monsters, Weirdos & Creeps cards. (they're still being cut & packed into their packs so they'll be mailed out by friday!) 27 different cards with a different Monster, Weirdo or Creep on the front & then a comic, some weird art, a profile of a cool dude (Ed Roth for example) or a culturally important item (pinball, coney island, hot dogs) on the back. 7 cards to a pack. Secret additional cards will appear in any Goblinko releases for the rest of the year.
My little brother Daniel (aka Danny James) formerly of the Cuts, now doing solo music came up with the boogers & blood concept when he was working on his master's thesis in advanced brattyness at age 9, after noticing that big juicy boogers have blood on the end of them frequently.
