From the 1930s onwards Dutch artist M.C. Escher produced many drawings with paradoxes of perspective. In 1957 he produced his first drawing containing a true impossible object: "Cube with Magic Ribbons". He produced many other drawings of impossible objects, sometimes with the entire drawing being an undecidable figure. His work did much to draw the attention of the public to impossible objects. Some artists of the time are also experimenting with impossible figures, for example, Jos de Mey, Shigeo Fukuda, Sandro del Prete, István Orosz (Utisz), Guido Moretti, Tamás F. Farkas and Mathieu Hamaekers.
