Aurora Model Kit Set of 3 Monster Vehicles (Boxes Only). Aurora, 1964. Aurora Plastic Corporation continued with their series of Universal monster kits, but with the company’s primary focus on cars and planes, they jumped on the horror bandwagon and produced a series of monster cars. These are the highly sought boxes for these three kits in excellent condition. This lot is for the boxes only; the contents are not included except for the Mummy instruction sheet. 13 ¼ x 5 ¼ x 2 ¼”. Very good.
