Photographic print of a postal worker

A black and white photograph of a postal worker sorting mail into cubby holes. The postal worker stands in front of two large shelving units divided into smaller sections in a large post office. Two of the individual shelves are labelled for different areas of California and Kansas; the other visible labels are not legible. Two large boxes of chicken eggs sit on a counter to the postal worker's proper right. The back of the photograph has a barcode sticker from that reads: [File: 51-1491 / ID: AP179 / Neg.: / Credit: Pittsburgh Courier Archives/Archive Photos NR / An African-American postal worker stands and sorts mail into separate slots at the downtown branch of the U.S. Post Office, Pittsburgh, Pennsylvania.] At the center of the back of the photograph there is a yellow dot sticker.
