In 1924, he met Sally Michel, a young art student, and in 1926, they married. Her income as an illustrator enabled him to devote himself more fully to painting. The two had a daughter, March Avery, in 1932. For several years in the late 1920s through the late 1930s, Avery practiced painting and drawing at the Art Students League of New York. Roy Neuberger saw his work and thought he deserved recognition. Determined to get the world to know and respect Avery's work, Neuberger bought over 100 of his paintings, starting with "Gaspé Landscape", and lent or donated them to museums all over the world. With Avery's work rotating through high-profile museums, he came to be a highly respected and successful painter.
