Here are two shabby and aged vintage postcard backs.
The first card is a dark golden yellow color with a dividing line for correspondence and address down the center. The main wording is also centered and there are pretty swirls included in the design of the words: Post Card. 
The second postcard back is shabby white with yellowing throughout. The front of this postcard includes embossed roses and the embossed shape of those roses shows through on this back side of the card. The writing on the card is dark green and the dividing line allows about one-quarter of the card for correspondence and three-quarters for the address. Below the wording Post Card is included: Authorized by Act of Congress of May 19, 1898.
