Standard Screw Fastened Boots and Shoes 1881 Trade Card antique rebus I have a hard timeI love the expression on the monk here I guess meant to be St. Crispin, patron saint of cobblers who looks positively rabid at the sight of the Standard Screw Fastened boot dangled in front of him! And the mustache on our knight is pretty great too! Just a fun one, but also from what I can tell a rare one, with a handy 1881 calendar on reverse! 6" x 3 3 8" and in very good condition.
