The "Batwing 66" is an iconic type of roadside architecture from the 1960s, gas stations built across the country by Phillips 66. Most were designed with one "wing" but some have two. I love these structures, and I enjoy looking for them when traveling across the countryside.
The stations were designed by Clarence Reinhardt, who is otherwise unknown. The type is also known as the Harlequin 66, because of the butterfly resemblance.
Are there are others in Wyoming? Probably. Please comment with other examples!
