This vintage 1971 patch was found for $2 in an antique store's discount bin. I have no idea who created it, but it's not hard to see why. According to Peanuts Wiki, the illustration is from the July 4, 1969 Peanuts comic. "Lucy van Pelt had skinned her knees while roller skating. Asked by her brother Linus if she would skate again, she informed him that she had given her skates away." The final comic is Snoopy imagining himself to be a world-famous roller derby star. The comic would have been highly popular in the roller derby community when it came out and was likely posted at various training locations. So it could have been just about anyone who made it into a patch.
