"Hallows Angels" vintage Halloween biker patches! The Hallows angels patch set features a jack-o-lantern/pumpkin, skull, black cat, owl, scarecrow, witch, spider and vampire bat!
Inspired by the annual tradition of Halloween decorations which struck me as a sort of biker gang taking over your town -- but in this case it was a haunter gang. And each gang needed it's own "colors" (biker slang for jacket with back patches).
Each name was exhaustively crafted to relate to Halloween as well as sound like it could be an actual outlaw motorcycle club!
