In 1940, Fenton started selling Hobnail items in French Opalescent, Green Opalescent and Cranberry Opalescent. The bottles were made in French opalescent glass with the hobnail pattern. The legionnaires of the Roman Empire wore hobnail boots, called "caligae". The clinched hobnail ends were covered by an insole. The shop was founded as "Holts" in 1851, selling hobnail boots. In some areas they may have a hobnail appearance. In 2010, Hobnail released a virtual 13 disc release "Unsurpassed Broadcasts".
