I love finding this kind of stuff floating around on the internet. I think it was Liorcifer who posted it over on Last Sparrow; filmed at a tattoo convention in St Paul Minnesota in 1978, featuring Elizabeth Weinzzirl, Spider Webb, Bob Raven (I think? Hairdresser who worked on the Strip with extensive Cliff Raven tattoos) Vyvyn Lazonga and more.
The old guy with the pencil thin mustache steals the show. Anyone have any idea who he is?
