Very unique piece. I purchased this at the Brimfield Antique Show, the story I was told was that it was cleaned out of a storage/salvage building in Boston. I haven’t been able to find any photographs to tie it together, so it’s just unsubstantiated folklore. I believe it’s a street sign based on the rear mounting post holes. Shows considerable wear and oxidation. Please view all 24 photos for measurements and condition. Insurance and signature confirmation included on domestic shipping charges.
