The H.D. Lee Mercantile company was founded in Salinas, Kansas, in 1889, but by the early twentieth century, it was focused on making clothes and had factories in several cities, including Trenton, New Jersey. Lee Union-Alls, a jumpsuit for mechanics and other blue-collar workers, were created in 1913 and became their signature product. The name touted the fact that they were union-made.
