William Gray Purcell (1880-1965) was an architect who was hired by Alexander Brother's Leather Belting Company. In addition to architectural duties, Purcell acted as their advertising manager from 1916 to 1918. These colorful items in this collection were possibly covers designed for trade catalogs or publications. They are all copyrighted 1917, designed in a modern style, and may have been commissioned for the company's commemorative fiftieth anniversary that year.
