Here are two pix which may be of interest. They are tiny model kits, a breakfast cereal premium, issued sometime in the 1970s.
I purchased them at a flea market in the 1990s, and know nothing else about them. They are some sort of space vehicles, however, and I do plan on "building" and painting them one day.
I wonder if the designs are reminiscent of anything in the Project Sword, Space-X canon? These are small – probably a little over one inch long when finished!!
