This vintage plaid wool workshirt was made in the early 1930s and was sold by R.H. Macy & Co., Inc. They later simplified their name to Macy’s. The design of the shirt, in particular the distinctive pocket flaps, are consistent with what was being produced by LL Bean at the time. It’s likely they had the contract for this Macy’s store labeled shirt.
