I agree with ekuw that it is more valuable as sports memorabilia. Keep it safe.
Very unique quilt and looks all hand pieced and 'tie quilted'.
Without seeing the back of the quilt I don't know if the cross hatch stitches
go through to the back or are just on the front. I see that they have been
used on the binding also.
You could contact a local museum and see if they have or know of a textile
expert to look at the quilt. Your local college or Junior College should also
be able to give you the name of someone to help.
It has places that need repair, but don't do anything to it until you get it evaluated.
Keep it safe and good luck.
Oh, and please let us know what info you find.
