Shirlie had a friend who was a Rennaissance man of sorts ... an author, a photographer, an inventor, a book publisher and a dabbler in politics. Hal Stewart. This is a letter from ex-President harry Truman in Dec 1956 responding to a request ... or inquiry ... from Mr. Stewart. (At the time, I believe, Stewart was pursuing with the military an invention of his for an early warning air raid detection system/alarm.)
What makes this letter interesting is that ... one, it does appear to be Truman's actual signature, and two, his lament that he is no longer insider. (The image is poor, as I scanned this years ago when memory was precious.) The letter reads:
Dear Mr. Stewart:
In reply to your letter of the 14th, I am sorry I am not in a position to give you any information on this subject. I have been a complete outsider since January 20, 1953.
It seems to me that the best approach would be to contact the ?? Research Institute yourself and tell them what you want.
It is a great institution and has made many very valuable contributions to the welfare of this country.
This letter is in a private collection.
