This folder contains letters congratulating Edison on the celebration of his sixty-seventh birthday. The selected sample consists primarily of letters from dealers of Edison phonographs and dictating machines, including Peter Bacigalupi of San Francisco. Also included is a photocopy of a biographical questionnaire filled out by Bacigalupi.

Less than 1 percent of the documents have been selected. Most of the items not selected received no response from Edison. Some bear his marginalia, indicating the reply of a simple "thanks."
