Did the Czech firm Inwald produce car mascots (radiator ornaments) in the manner they produced flower frogs? I have a green satin glass fish, identical to the fish shown in this forum. The difference, however, is that a metal cap on mine is affixed to its undersidr. It is more like a car mascot than a flower frog. My tentative hypothesis (purely a guess) is that perhaps Inwald produced car mascots in the 1930's or so, but when car mascots grew out of favor Inwald used the same molds to produce flower frogs. In any case, the green satin glass flower frogs by Inwald are identical to my green satin glass fish with the metal undermount suitable for mounting on a radiator. Any thoughts on this?
