For your consideration we have a wonderful vintage pinback from the 1940s. The dates of Jan/Feb/Mar 1941 are on the top of the button with the BMWE in the middle and the words Affiliated AF of L and TLC of C underneath. There is small scrape over the "ar" in March. This is just a great union pinback and a perfect accessory to anyone into the vintage workwear look. Note the adornment of hats and caps in the last two photos.
