title: Origin and history of the "Series B" and "Series C" TAT pictures.
abstract: I present the origin and history of the "Series B" and "Series C" pictures of the Thematic Apperception Test (TAT; White, Sanford, Murray, & Bellak, 1941; Clark, 1944). I fill in the evolutionary gap between the "Series A" pictures (W. G. Morgan, 2002) and the 1943 "Series D" (W. G. Morgan, 1995, 1999). Here one can observe which cards were retained from series to series, what new cards were experimentally introduced, and which cards were resurrected after a period of disuse. It would seem that only the world shattering events of WWII were enough to halt this evolution and freeze the content of the TAT at the time of Murray's departure from the Harvard Psychological Clinic to join the Office of Strategic Services.
