Casto and company went on to develop several sprawling retail hubs in the suburbs surrounding Ohio's capital. These included GREAT WESTERN SHOPPERS MART, GREAT EASTERN SHOPPERS MART and the GREAT SOUTHERN SHOPPERS CITY depicted here. It opened for business in 1957 and -in June of 1962- hosted the very first Woolco discount department Store.

At the time of this circa-1968 snapshot, the TOWN & COUNTRY Union Company has just emerged from a renovation that has doubled the size of the store.
