This vintage Teamsters pinback button proudly displays the organization's name at the top, along with the specific Local 20 designation. The central graphic features the classic Teamsters emblem of two horse heads flanking a wagon wheel, encircled by the full original name, "B. of T. C. W. & H. of A." (Brotherhood of Teamsters, Chauffeurs, Warehousemen and Helpers of America), indicating its historical significance prior to the later International Brotherhood of Teamsters (IBT) naming.

The button is constructed with a celluloid over tin design, presenting a vibrant pink background accented with white and yellow, and crisp black lettering. The reverse side features a secure straight pin attachment, and the maker's mark "GREEN DUCK CO. CHICAGO" is clearly visible, a known manufacturer of quality union and political pinbacks from the era. This collectible piece offers a glimpse into the rich history of the labor movement and the Teamsters union, making it a significant item for collectors of union memorabilia, labor history artifacts, or vintage pinback buttons.
