This unused linen postcard features an a view of
Whitfield Auditorium in Columbus, Missisisppi.
According to Mashburn's The Postcard Price Guide, A Comprehensive Reference,
the Linen Era postcards were produced between 1930-1945.
We can be fairly certain that such "bird's-eye" views were still on the novel side, air travel not yet being common yet. The paper has a linen-like texture, which gives this type of card a distinctive appearance.
