Hello.  Looking for thoughts on this Jack Swigert signed stationary from shortly before his passing.  It's signed with his first name only, and I blurred the name and address of the recipient on the scanned image.

The "Jack" looks a little atypical, but it looks good overall to me.  Still, I'd like other thoughts.  I wasn't sure if he had a secretarial signer late in the progression of his cancer, or after winning election to the U.S. House of Representatives.  Thanks for your thoughts!
