These are Miniroc flying rocket models that were photographed for the covers of retail kits of Model Products Corporation. They were built of wood and cardboard in 1971 and were evidently photographed that same year. The manufacturer is unknown. G. Harry Stine, an American pioneer in the field of flying rocket and missile models, donated them to the Museum.
