Rennert’s Gallery is one of the world’s only galleries/auction houses dedicated to the art of the poster. Located in Manhattan’s Flatiron / Union Square, we host auctions of high-quality, rare poster originals three times per year, specializing in original Art Nouveau, Art Deco, and Mid-Century Modern lithographs. Founder and president Jack Rennert is one of the world’s leading authorities on vintage posters, the author of over a dozen books on the subject, and consultant to museums and elite collectors around the globe.
