This week's collection is small but perfectly formed. Kiki Werth is a London-based poster dealer who has specialised in original vintage posters for over 30 years. The travel and information posters in her collection mostly date from the mid-20th century and are superb pieces of graphic design. Russian, Swedish and French designs sit beside those from Poland, the Caribbean and Spain, and give a well-travelled flavour.
