The reverse side of the photograph clearly indicates its origin from Harold K. Vollrath's collection, located at 8938 Maple Drive, Shawnee-Mission, Kansas, and notes that "Reprints are Available.". Handwritten notations on the back include "Tep 331," "D-9 Cache 1103," and "Pleasant Hill Lz 10-34," strongly suggesting the image dates to October 1934.
