"The Boating Party," painted in 1893-94, is one of Mary Cassatt's most ambitious and celebrated works. The painting's bold composition, with its flattened perspective and strong blocks of color, shows the influence of Japanese woodblock prints, which were highly fashionable in Paris at the time. The subject matter, a mother and child with a male rower, is typical of Cassatt's focus on domestic and maternal scenes. However, the painting's large scale and powerful execution elevate it beyond a simple genre scene. The issuance of this stamp in 1966 was a significant recognition of Cassatt's importance in American art history, at a time when female artists were often overlooked.
