10. 'A Woman Bathing in a Stream', 1654, by Rembrandt van Rijn


It's peak tourist season for London's art galleries, which means postcards are flying out of the racks. In our age of Twitter, Instagram and general can't-be-arsed-ness, actual postcard writing may be a dying art, but we still love to pick up miniature versions of the best paintings in London (for around 70p each) to adorn our walls - or just languish in drawers. Here are the top ten postcards based on sales over the past year at the National Gallery.
