Our friend the Lunar Rocket Ship, this time by Park Plastics of New Jersey. Did they do any more space toys? [pictures; Ebay]
WOTAN BUTTS IN AGAIN:
Parks made a number of air/water powered rockets too like the Merit Lunar Rocket. A polythene rocket is pumped up with compressed air after addind a little water and the water is ejected shooting the rocket high in the sky.
I also came across these cool Moon Vehicles some while ago and subsequently found a packaged version called the Lunar Dump. Nice.
