It took me a long time to spot the well in this picture. Phillips 66, ad from Playboy, November 1976.
My grampa died a few years back. Then my grandma died. Between the two of them I inherited three cartons of cigarettes that were probably 15 years old, and several boxes of smut rags from the 60s, 70s, and 80s. I can't post smokes, but I might as well post some of the ads from the smut rags.
