Oddities & Curiosities Expo is a traveling marketplace and exhibition that brings together vendors, collectors, artists, and performers offering taxidermy, natural history specimens, vintage medical artifacts, cabinets of curiosities, and oddball artworks. The Denver edition takes place at the Colorado Convention Center and combines vendor booths and curated displays with sideshow-style performances and talks that appeal to collectors and fans of the macabre and unusual. The event is notable for assembling rare, handmade, and historical curios that foster a community around dark art, occult ephemera, and alternative collecting.
