Mystery Man

An unidentified man sitting at a desk (the photo is among Stellan's Bayou Teche pictures). A large blow-up of the poster behind the man's head advertizes the 1916 movie Joan the Woman starring Geraldine Farrar and directed by Cecil B. DeMille. The two pictures of DeMille shown below bear a resemblance to the man shown here; what his connection with Tarzan may have been I do not know. On the other hand, maybe it's Edgar Rice Burroughs. He "was on hand during the shooting to make sure that his novel wasn't distorted." (Gabe Essoe, "Tarzan of the Movies," p. 14)
