See previous related item. 1.25" with covered metal back and fixed horizontal bar pin plus on curl can be read the name of maker "Photo Jewelry Mfg. Co. Chicago." Reverse has tiny 1/8" spot where the cello and paper were not long enough to fold under the metal back and while this is all quite tight it does make a very small bump when the button is viewed from the front. The button itself is otherwise incredibly clean and glossy condition with almost no surface wear even under magnification. Button displays Mint with the small edge bump as made.
