A circa-1959 view of the West Plaza. In place of the old TG & Y, beauty-barber shop and bakery are Youth Center, Schiff's Shoes and Peyton-Marcus (an OKC-based women's ready-to-wear store).

The cars date this West Plaza snapshot to about 1968. By this time, Peyton-Marcus has expanded into two adjoining store spaces. The Conrad-Marr Drug and Humpty Dumpty grocery -1940s charter tenants- are still in business.
