As you know I'm a sucker for possible origins of space toys and box art. Waiting for our Friday curry delivery I browsed past auctions on Liveauctioneers. Well guess what! Take a gander at the JR21 X-60 Space Rocket on Launching Truck [top picture] we know and love and compare it with what is it's first appearance on the blog, the yellow Ideal Space Fighter Transport XP-19 (made of molded plastic) [very bottom of picture]. What do you think?
