This is a Kartell modular trolley, model 4970, designed by Anna Castelli Ferreri in the late 1960s. These iconic containers are famous for their versatility and were made in Italy. This one is particularly valuable because it is part of the "first series" produced in the late 1960s, as can be seen from the imprinted logo, which at the time did not yet contain the model code. This piece has an attribution mark, I am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution
