From the bygone glory days of the 5 & 10, we have two examples of a dual dime store mall. The first, Nassua County, New York's GREEN ACRES CENTER, housed F.W. Woolworth and J.J. Newberry locations.

Our second example, Phoenix's CHRIS-TOWN CENTER, had F.W. Woolworth and S.S. Kresge stores under its roof.

From several years earlier, we have "The 5 & 10 cent store" poster. It was created under FDR's New Deal Federal Art Project (1935-1943).
