I have an inherited, from my father, a lifer in the US Air Force, one autographed, Apollo 11, white suited Neil Armstrong lithograph.. I've researched and I have seen many of Neil Armstrong's autographs.  I know mine is an original in person autograph, what I don't know is the handwriting on the back...is it Mr. Armstrong's or my fathers?  It doesn't resemble the handwriting I remember of my father, but I cannot find any handwriting examples of Mr. Armstrong other then his autographed signature.

Any ideas?
