Shenango for J.E. Stephens Co Luncheon Plate

This vintage Shenango China luncheon plate was made for the J.E. Stephens Co in Detroit (who is hard to find information about but was most likely a company who provided goods for the hotel/commercial industry). Sold as open stock (single plate), there are heavy utensil marks on the surface; some presenting as gray veining. There are no chips or cracks. Measuring 9" across, it is in overall good condition.
