Souvenir postcards showing the dioramas (above) made by Frederick Blashke for the Field Museum of Natural History’s (now The Field Museum) “Hall of Prehistoric Man.” The exhibit, featuring life-sized figures, was instgalled in 1933. In 1973, the Blashke figures deemed out of date based upon more recent paleoanthropological information, the Neandertal family group was replaced with a new diorama by Joseph Krstolich (below). The hall has subsequently been closed and the dioramas dismantled and placed in storage.
