The Roan pressbook in the LD set dates from the late 1930s. An original (with other documentation that mentions it) appears in Krellberg's papers at the Library of Congress.

As the film made the rounds heavily in 1934 on something of a low level "reissue," it is possible that the abbreviated press sheet in question actually dates from that period.

Regardless, though, it was in use by 1938.
