Frank Zappa with his famously dense mustache and soul patch

Musician Frank Zappa looks up from a book or music score in this casual photo taken sometime around the year 1971. Frank Zappa was born in 1940, so he would likely have been in his early thirties when this photo was taken. 1971 is the year that, per Wikipedia, Zappa and his reformed band The Mothers of Invention released "the double-album soundtrack to the movie 200 Motels, featuring the Mothers, the Royal Philharmonic Orchestra, Ringo Starr, Theodore Bikel, and Keith Moon."
