While I was still on the WPA I was submitting designs for the Section of Fine Arts competitions which I did on my own time. Burgoyne Diller gave me a mural to do in the Community Building of the Queensbridge Housing Project on Long Island. I worked on the design and cartoons for about a year. Everything was approved and the walls prepared - casein tempera painted on the wall.... [It was] about 1938. Holger Cahill asked me through Diller to do the outdoor facade mural of the WPA Building at the World's Fair. 1 stopped work on the Queens mural and began working on the Fair mural which was finished on schedule in time for the opening of the Fair.
