Between 1936 and 1938 Sebree worked for the WPA easel division, participated in the South Side Community Arts Center, and was involved with the Cube Theater. He maintained a strong interest in the theater due to his friendship with Katherine Dunham. Guided by her influence, he explored set and costume design, theatrical production, writing, and dance, while continuing to paint. Sebree was also close with a group of bohemian artists from Chicago and Wisconsin, which included Magic Realist painters Gertrude Abercrombie, John Pratt, John Wilde, Karl Priebe, and others. Sebree began writing plays in earnest in 1949- his most well received work was Mrs. Patterson, which opened on Broadway in 1954 starring none other than Eartha Kitt. In addition to all of his creative endeavors, Sebree also collaborated with Harlem Renaissance author Countee Cullen by illustrating his narrative poem, The Lost Zoo (A Rhyme for the Young But Not Too Young).
Sebree’s work has been featured in multiple exhibitions at the Art Institute of Chicago and was also featured at Katharine Kuh Galleries, Chicago Artists Group Galleries, American Negro Exposition, South Side Community Art Center, Howard University, Chicago Public Library, Kenkeleba House, and the Woodmere Art Museum. His work is found in many prominent collections including Howard University, Smithsonian American Art Museum, St. Louis Art Museum, and University of Chicago.
