This originally popped up on The Heads of State's Twitter feed yesterday.
Christies is currently auctioning http://this "1978" Sex Pistols flyer. But a closer look reveals what looks an awful lot like Comic Sans, released in 1994.
So, is the flyer a fake? Or was Comic Sans drawn from an older face? And not to get all "Type I.D. Board" or anything, but do any other letters here seem out of place for 1978?
