The exhibition consists of sculpture, paintings and roto-peintures which are 3D pieces with panes that move. All the works were created between 1928 and 1968. The exhibit is accompanied by a 60 page catalog.
The exhibition is titled Φ, the Greek letter Phi—which is a symbol that was integral to Folmer’s work beginning in the 1930s. It is the symbol of the mathematical theory, The Golden Ration. It signifies the balance of all things. Folmer used it to sign many of his works.
