Because I can't say no to red cross logos on most any old thing, and its a rare thing to find a whole bag of pins, with a nice variety here, too. Mostly 1930s I believe, a few dated as such, and perhaps the two larger (upper left first photo) WWI era. Plus a Junior Life Saving patch, c. 1930. 20 pins total plus patch, all pictured and all in good shape.
Small cross pins: 5/8" d. Larger crosses: 7/8" d. All pictured included.
