Stamp

The label, or brand, of a glassine bag of heron. The joke is cut & bagged at a high level in bags made by folding wax paper into neat squares, and usually taping these shut. In the Northeast, and particular NJ, Bronx & Manhattan where the trade is centralized & huge mills turn out millions of stamps, each mill will use a unique design and brand name. Sometimes the art, word play and irony are museum worthy, if not pc.
