Twentieth Century Posters is an antique poster gallery founded by David Bownes, the former Head of Collections at London Transport Museum, Director of Collections at the National Army Museum, and the author of several books on poster history. Twentieth Century Posters offer a selection of original, authentic, posters and related artwork, ephemera and books featuring graphic and information design from the last century, with a focus on British commercial art.

"My passion for posters began in childhood and I’ve been fortunate to spend a career curating some of the most significant collections in the UK.
