Apollo 13 astronaut Jack Swigert autograph w/ JSA letter of authenticity

Description

Fresh to the market is a newly discovered autograph of Apollo 13 astronaut Jack Swigert. AU is on the back of an old NFLPA dinner pamphlet. Found at an estate of a Bears fan in Illinois, the cover is also autographed by Chicago Bear lineman George Seals. Let it be known, the JSA authentication
only
goes to Mr. Swigert's AU.
Jack Swigert's autograph is bold and strong. It has been touched in a few spots (please see pics). It's on the back of a NFL players association dinner pamphlet in which he was a guest speaker back in 1970.
So is the autograph on a document attributed to NASA? No. Is it on a picture or on anything related to space? No.
Hence, the lower price than the other Jack Swigert autographs.
In theory though, if you created a cut of this and married it up to a piece attributed to Apollo 13 this is a great, affordable piece of space history to add to a display.
