Halloween party fliers from the Johnny Science papers, c. late-90s. Scanned at NYU Special Collections.
I know, given the context in his papers, that Johnny Science created the flyers for the Jovian Gentlemen (which was a group he founded for matching 21+ men interested in middle aged to old men) and the flyer for the Lesbian and Gay Community Services Center Dance Committee (particularly interesting to me, as I had no knowledge he had ever worked with them.)
Less clear to me are the origins of famed lesbian party promoter Caroline Clone's Nightmare on 8th St or the Radical Faeries Xtravaganza. I believe he may have created the flyer for Clone's party due to the style but I scanned these quickly so I may be misremembering. I don't think he made the Radical Faeries Xtravaganza flyer.
