Lot of three vintage metal campaign and union pinback buttons related to Morrell workers and Sioux Falls labor organizing.

The yellow and red anniversary button reads 'Sioux Falls' at the top, 'Grow Together' across the center band, and 'Morrell' at the bottom with the years 1909 and 1954, printed on a bright yellow ground.

The cream colored support button is printed with the slogan 'I Support the Morrell Workers' in black lettering, while the multicolor button shows a stylized flag and large number 86 with circular text reading 'Local 304A Active Ballot Club' and 'United Food & Commercial Workers' around the edge, plus a small union bug logo along the lower rim.

All three buttons have metal backs; two include horizontal safety-style pin fasteners with light surface wear, and the Sioux Falls anniversary piece has a heavily rusted back and no attached pin so it is best suited for display instead of wear.

Notes: Listing includes only the three political and labor union buttons pictured; no original cards, packaging, or additional accessories are included.
