This is a promotional postcard available from the restaurant chain known as the Chicken Shack. This is a common name for restaurants in the United States, but this one, subtitled Leslie’s Fried Chicken, was founded in Waco, Texas.
The description states:
THE CHICKEN SHACK
Specializing in Famous Leslie’s Fried Chicken
Famous for large, tender prices of chicken, fired to a crunchy, golden brown and served piping hot. Every one is welcome. Come as you are traveling and enjoy a meal of Leslie’s Fried Chicken in our large air-conditioned dining rooms, or take it with you, packed in a neat box.
–The Waco establishment was closed in 1996. The cars in the picture indicate it dates from the 1950s.
