Like everything we are selling, this was a family item, from my father who was born in 1930, so our best guess is that this mitt is from the late 1930's or early 1940's.  I can verify that the gromets are intact, and everything is original.   The original owner's initials, OJL, are embossed in two places on the front and "Oliver L" is in ink on the wrist strap.   The leather on the inside of the glove is in good (for the age) condition, with the exception of the middle finger, where worn leather can be felt.  The exterior leather has the expected scuffs for a mitt this old, but no rips or holes that I can see.  Stitching appears intact with the exception of the leather trim just above the wrist strap, which I have pictured.  The glove was stored in a basement, and when sniffed up close smells musty.   I do not see a brand or player endorsement stamp.   Please review photos carefully, and ask any questions before purchasing.
