This is a pretty little linen type postcard with a view of downtown Clarksdale, Mississippi. Since it was never used, there's no postmark to give away its age.... But take a look at those cars and see what you think!
According to Mashburn's The Postcard Price Guide, A Comprehensive Reference,the Linen Era postcards were produced between 1930-1945. The paper has a linen-like texture, which gives this type of card a distinctive appearance.
