The collection includes correspondence, notes, postcards, travel journals,
photographs, and motion pictures of Field's journeys throughout the Soviet Union,
especially Georgia and its upper Svanetia regions, from 1928 until the 1970s.
Field's partially indexed photographs and films contain images of Moscow and the
Caucasus, mostly from 1929 to 1934, documenting local architecture, geography, and
people. The collection also includes a series of 1931 letters from Upton Sinclair
and others requesting financial assistance for Sergei Eisenstein's uncompleted film
about Mexico, Que Viva Mexico.
