This miniature publication presents forty-one black-and-white reproductions of collection works, shown at the Guggenheim's then-new home at 1071 Fifth Avenue, New York, prior to the construction of the current Frank Lloyd Wright building. Included in Art of Tomorrow are Rudolf Bauer, Robert Delaunay, Emmet Edwards, Albert Gleizes, Vasily Kandinsky, Alice Mattern, László Moholy-Nagy, Otto Nebel, Hilla Rebay, Rolph Scarlett, Vladimir Schwab, Georges Valmier, and Jean Xceron. Also included in this publication are two installation photographs of the former Museum of Non-Objective Painting, as well as installation views of the Kandinsky Memorial (Mar.–Oct. 1945) and the Moholy-Nagy Memorial (May–July 1947).

While objective painting appeals to the senses and intellect, Non-Objective or creative painting appeals to soul and intuition. This appeal touches the soul to the degree of its depth and its advance in the control of the senses. The rhythm of the inbetween [sic] creates the work of art.

These paintings elevate the onlooker through pleasurable realization of aesthetic refinement to harmony containing order, which proves satisfying to the soul’s need for perfect place.
