While the Boom! Peanuts series has had rare alternative covers for each of their issues, some of them have had other variant cover editions. These are ones meant for sale at specific conventions. Next up is this year’s Emerald City Comicon, in Seattle March 1 through 3, and I think the Vicki Scott-drawn cover for that one is pretty cool.
They’ll be making 500 of these available, at $10 a pop.
