Lewis Larsen was one of the pioneers of modern North American archaeology. Along with Joseph Caldwell and Arthur Kelly, he supervised the archaeological studies at Etowah Mounds National Landmark during the mid-1950s. He then went on to a highly productive career as a professor and expert on the Mississippian Culture.
It would be very nice if this collection could be preserved intact.
