The picture above is an advertisement for the college bookstore at John Tarleton College in Stephenville, Texas. The year was 1967. They had quite a supply of cigars and pipes for Joe College, seen here in his white socks. Local businesses bought ads in the high school's or college's yearbooks and supplied pictures, usually with their employees and everyday customers, but relatives who were students that year were always included. Here's an ad in Biola University's 1973 yearbook.
You can't get much more '70s than that! Well, maybe if it were in color, we could see how the plaids did not actually coordinate with anything. See a gallery of yearbook ads from the 1960s and '70s at Flashbak. -via Everlasting Blort
