The object represented here is a toy that falls into a specific hobby category, that of model making, which after the Second World War, had a rapid increase thanks to plastics and new molding methods, such as injection molding thanks to which faithful details could be obtained even in very small formats: pieces of ships, airplanes and other vehicles that were previously made of wood, tin and other natural materials, were now produced in plastic, and in much higher quantities and at low cost. Our object belongs, among other things, to a particular sphere of modeling, which begins to spread with the success of the great Hollywood films. The big film companies, in fact, are beginning to sell to toy companies licenses for the production of merchandising which, together with the promotion of the same films, nourish the fame of characters who have become cult objects. To confirm this, the toy in question reproduces the character of King Kong, protagonist of the homonymous film directed in 1933 by Merian Caldwell Cooper and Ernest Beaumont Schoedsack. The polystyrene object is produced by the American company Aurora Plastics Corporation founded in 1950 by the engineer Joseph Giammarino and the entrepreneur Abe Shikes in Brooklyn. At the beginning of its activity, Aurora produced injection-molded plastic materials for third parties but in 1952 the company started the production of plastic models. As reported on the basis of the object, the King Kong belonging to the collection of the Plart Foundation was made in 1964. Aurora Plastics Corporation supplied, together with the assembly instructions of the various pieces that made up the kit, also the Styrene Plastic Cement, the 'adhesive that was used to glue the various parts of the model.
