I get a little giddy thinking about old-school horror collecting — if you like 'The Vampire Lovers', there absolutely are collector items, but it’s a very niche, treasure-hunt kind of scene. The most common official pieces are home-video releases: restored DVDs and Blu-rays from specialty labels, sometimes bundled in box sets with the other Karnstein films. Those editions often come with booklets, essays, and reversible artwork which make them collectible in their own right.
Beyond discs, the real vintage stuff lives in cinema ephemera: original posters, lobby cards, press stills, and pressbooks from the 1970 release. Those can turn up at film fairs, estate sales, or auction houses and are priced by rarity and condition. Reproductions and modern art prints are easier to find — Etsy and independent horror artists sell posters, enamel pins, and shirts inspired by 'The Vampire Lovers'. I’ve picked up a gorgeous lobby card at a weekend fair and it still sits framed in my den; it feels like holding a piece of cinema history.
