Authentic vintage Pinkerton’s Inc. regulation security shirt, manufactured by SetloWear and union made in the USA. This light blue short sleeve uniform shirt features dual chest pockets, classic shoulder epaulettes, and an original Pinkerton Security Service embroidered patch sewn onto the sleeve. Constructed from a durable 65% Dacron polyester / 35% combed cotton blend, it’s designed with perma-press and soil-release qualities for easy maintenance—ideal for collectors, costume use, or fans of US workwear and Americana. Dated via union tag to 1996, this shirt carries clear vintage provenance and is tagged size M (true to size). Condition is good with minor signs of wear typical of age (no holes or major flaws). A rare and genuine piece of private security history from one of the oldest US security agencies.
