At the time this postcard was made (probably early 1960s), The Spotted Horse Store & Service had a complete general store and post office that had served "True Wyoming Ranch Country" for 50 years. It was named after Cheyenne Indian Chief, "Spotted Horse." The building is now a bar and there is a different Spotted Horse in front. The post office was discontinued in 1964, and the address is now listed as Arvada, Wyoming.
The Post Office sign is to the right of the Spotted Horse name. There is a small red and blue mailbox to the right of the door. In addition to the large Standard Oil sign, many smaller advertising signs are visible. There are two beer signs--Falstaff on the left and Schlitz on the right. The right side of the building has two Coca Cola signs--a round red one and a bottle-shaped one. There is a Kool cigarette sign on the bench. To the right of the bench is a small 7up sign. The small signs next to the door appear to be more cigarette advertising for L&M and Viceroy cigarettes.
