This is one of several wooden door panels from a large storage facility locker from Boston Storage Warehhouse, which was in existence in the late 1800s near Boston Symphony Hall. Height is about 4' and length varies from 2' - 3' 6". Each panel is marked with a letter at the top and is two-sided. Each side includes a couple hundred hand painted numbers with small hooks where keys once hung. Great condition and usage wear. Very unique pieces.
