A collection of material by and about Washburn. Includes several accounts from his journeys, including his early visit to Europe with William Chase, as well as travel in Morocco, the Marquesas, and Mexico. The last includes both some material on the Mexican Revolution and a description of a bullfight he attended. Also included are some essays Washburn wrote on Mexican architecture and natural science, as well as a canceled passport and some letters of introduction from his brother, Stanley. Note that one pad of Washburn’s conversation notes has a very early sepia photograph of him pasted in the back. Also includes some memorial material, including a program from a memorial service and a copy of his eulogy.
