I don’t have much information on this image other than that it was sourced from a newly acquired Kodachrome slide that dates back to the late 1970s and features Sailor Sid Diller at an unnamed San Francisco tattoo show. Photographer, event organizer, (convention? show? his name tag turns to a blur when the image is enlarged) and all other relevant data may be lost to the ages, but at least the image, some forty plus years old now, survives.
Early tattoo conventions were an integral part of the tattoo community developing and expanding before the rise and eventual decline of the tattoo magazine and the ubiquity of the internet, but they often ostracized attendees who were also in the emerging body piercing scene. Still, they provided a space where devotees could meet at local (often gay leather) bars near the convention or in hotel suites to share their passions, and slowly but surely the two subcultures merged and became part of a bigger community.
