Warm.meals.at.all.hours: Wonderful Early 1900s Family Lunch Counter Advertising RPPC With Sow

I found a good handful of photographs in Pennsylvania I really love, and this very much one of them, which I'm quite tempted to keep for myself and hang in the kitchen. Family Lunch Counter. Warm.meals.at.all.hours. (another example of an excellent use of periods separating each word!) And then this this fat sow with very swollen udders, black almost like a silhouette against the the wonderful horizontal lines of that fence. Fabulous. 

5 1/2" x 3 1/2". Early 20th century, unused postcard back. Very good condition.
