Inspired by space exploration and the earthly delights of gardens and music, Alma Thomas created brilliant abstractions that place her among the most innovative American painters of the 20th century. She had broken from realism and moved through expressionism to abstraction before developing her mosaic compositional style and reveling in color theory. Thomas improvised with light, color, rhythm, and an aerial perspective that interpreted her world in a new way. After retiring from a nearly four-decade career in art education, Thomas reached her mature period as an artist. In 1972, at age 80, she had a solo exhibition at the Whitney Museum of American Art, the first African American woman to do so. With dazzling paintings like the 12 collected in this calendar, Thomas left her mark upon the history of modern art.
