Your letter was received in due time and I was glad to furnish the autograph you requested.
If you should require other material or photographs I suggest that you write to our Public Relations Department for such information. I also refer you to my autobiography THE STORY OF THE WINGED S which will give you a good history of my life’s activities in aviation and the story of our organization.
