AI-assisted research suggests this is an original 1920 Wolverine Brass Works sales and advertising packet from Grand Rapids, Michigan; however, details should be independently verified.

This lot consists of a cohesive group of early 20th-century plumbing trade ephemera, including a dated September 16, 1920 company letter, multiple illustrated advertising circulars, product sheets, order forms, business reply cards, and a mailing envelope. The pieces were clearly issued together as a dealer or customer mailer promoting Wolverine’s line of “high grade plumbing specialties.”

The illustrated sheets feature detailed engravings of compression bath cocks, basin cocks, stop cocks, and “Sure Seat” tank balls, offering a strong visual appeal alongside technical product information. The inclusion of unused order forms and reply cards adds to the completeness and desirability of the group, as these were often discarded after use.

Wolverine Brass Works, based in Grand Rapids, Michigan, was an established manufacturer of plumbing components, and material like this reflects early industrial sales practices and direct-to-trade marketing in the 1920s.

A well-preserved and visually interesting lot, ideal for collectors of advertising, plumbing history, industrial paper, or Michigan-related manufacturing ephemera.

Authentic period piece related to family, history or local heritage - well-suited for historical collections, genealogical /genealogy research, or museum acquisition.  Vintage or Antique.
