An unusual gift of Russian prints to the British Museum

In March 1926, at a time of cautious diplomacy between the Soviet Union and Britain, the British Museum in London received a gift of 218 Russian prints presented by a group of 20 Russian artists. The impetus for the donation was a gift of prints by the British artist Frank Brangwyn to the Moscow Museum of Fine Arts in the late summer of 1925. Were these donations intended simply to augment institutional holdings, either those of the British Museum or of the Moscow Museum of Fine Arts, or was the exchange arranged to bridge political and cultural divides?
