This trolley was designed by Luigi Massoni for Guzzini, in Italy during the 1970s. The trolley features two trays, made of off-white plastic. The two removable circular trays sit within the triangular structures with white wheels. The trays have a diameter of 56 centimeters. One wheel loose. The entire structure can be disassembled. In original and good vintage condition. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
