This is an authentic early 20th-century commercial printing plate featuring a detailed comb illustration, marked “Aluminum Manitowoc.” Plates of this type were used in letterpress and advertising production for catalogs, packaging, or trade materials.

The elongated format and finely engraved teeth strongly support its identification as a comb-related advertising or product plate, likely tied to grooming or personal care goods. Pieces like this are increasingly collected for their industrial craftsmanship, typography, and graphic design, and are commonly displayed as standalone objects in studios, offices, or print-themed collections.

This example retains its original copper-faced surface on a metal backing and has not been altered, preserving its authentic working character.

Dimensions: approximately 3 x .5 inches
