This vintage shirt was made in the 1930s and sold by Gronfein and Schwartz of Butte, Montana. It is made from Silk Radium, a fabric popular from about 1905-1935. It was a specially treated silk, developed to be extremely light weight, marketed as a summer shirt. It was an extremely expensive shirting material, selling for about four times what a comparable cotton shirt would. The shirt is cut long in the body, with gusseted side seams. It has small mother of pearl buttons, and a long 3-3/8″ spearpoint collar.
