Here's COURAGEOUS CAT from circa the mid 1960's. Made by Collegeville. Famous for being created by Bob Kane, of Batman. Just the body suit, no mask or cape (which it originally came with). Great hero graphics. It needs a bit of ironing, heat only. Many light stains, a rainshower or sprinkler? Some loose threads. Leg tear/snag. The only mask I ever found was crap, but the same mold was reused later, just a different paint job (see picture). Look for it!
