PP stands for Poly Plastic, a company based in Monaco which produced a series of simple 1/48th scale plastic toy cars in the late 1960s and early 1970s: Citroën DS 20, BMW 1602, Mercedes-Benz 250 SE, Alfa Romeo Alfetta. The models were made in many different colour combinations and are very similar to contemporary toy cars issued by CGGC Grisoni from Italy, but have different wheels. They were also sold in playsets along with plastic accessories such as road signs, traffic lights and petrol pumps.
