The H.D. Lee company was one of Trenton's foremost industrial companys back in the 20th century. With the shift in labor from the northeast to the south where labor was substantially lower, many industries left the area where they could produce on a more profitable level. Then along came overseas competition, and knocked out the southern labor market as industries moved off shore to China, Taiwan and other foreign venues.As I recall. H.D. Lee made "UNION-ALLS." a working man's denim overall.
