The London Transport Museum has it vast collection of posters online and many happy hours could be spend looking at them. For example, today’s poster by Mary Adshead, Country Joys on London’s Underground 1927, can be found on their site here. (This poster is also a tribute to the painting by Mary Adshead that was reproduced in the Sunday Times last Sunday to accompany the lead review of Young Anne: Portrait of Daphne Charlton 1935 was the perfect accompaniment to ‘young Anne’.)
