Rare Vintage 1932 Depression-Era & 1940s Teamsters Union Pinback Lot (3) - Ink Variants

Up for sale is an incredibly scarce and highly collectible lot of three (3) authentic vintage International Brotherhood of Teamsters (I.B. of T.C. & H. of A.) celluloid dues buttons. This grouping features two premium 1932 Great Depression-era pins with highly sought-after stamped-metal manufacturer variants, alongside a matching 1940s St. Paul Local 120 branch badge.

Included Pins & Specifications:

* 1932 March Dues Pin (Muted Green): Features the early dual horse-head spoke wheel design. Split-dated "19" and "32" on the front. The reverse features the Greenduck Co. Chicago hallmark stamped directly onto the gold-toned metal back in BLACK ink.

* 1932 April Dues Pin (Purple/Brown): Features the early dual horse-head spoke wheel design. Split-dated "19" and "32" on the front. The reverse features the Greenduck Co. Chicago hallmark stamped directly onto the gold-toned metal back in BLUE ink.

* 1940s Local 120 Dues Pin (Bright Yellow): Issued by the "General Drivers, Helpers & Truck Terminal Employees Local 120" out of Saint Paul, Minnesota. Features a clean, stylized graphic treatment.

Manufacturer & Production Highlights:

The two 1932 pins showcase spectacular, pristine reverse sides featuring the historic Green Duck Company of Chicago manufacturer graphics stamped directly onto the metal backs (not paper inserts). This includes their famous mallard duck trademark logo, the Feb 13 1917 patent text, and sharp dual Chicago union bugs. Finding these pins with matching clear graphics executed in two distinct colored inks (one black, one blue) makes this a premier manufacturing variant set.

Condition:

Incredible vintage condition for their age. The front celluloid covers are highly pristine with rich, vibrant colors, great gloss, and no face-splitting or cracking. The reverse direct-stamped metal backs on the 1932 pins are exceptionally well-preserved with clear, unsmudged ink graphics and negligible wear. The bare metal back on the yellow pin shows standard, age-appropriate surface oxidation. All pin mechanisms are fully functional. Please review the high-resolution photos for a precise look.

A premier centerpiece lot for any advanced labor history, Teamsters, or vintage Chicago Green Duck advertising collection. Will be carefully packaged and shipped promptly from the United States.
