W.R. McKeen Jr., Kodak No. 2 negatives, ca. 1891
These envelopes, dated November 4, 1891, contained 87 “good” negatives and 12 “failures.” The negatives were from a No. 2 Kodak camera. After 100 exposures were made, the camera was sent to the Eastman Company for processing. In this order, only 87 prints were returned to the photographer. The “failures” were segregated into a separate envelope and not printed. The Eastman Company provided a list of possible causes of the “failures” and the corresponding pages in the manual to help prevent them.
