Hi all, I am looking for some help please! My brother in law passed away recently and was a big Saints fan. In his possession was a signed football. I think I recall him saying that it was signed by a Saints team from the early 80’s but I am trying to research the signatures on it to determine and work out it’s value. I was planning on uploading some photos on here but can’t seem to figure out how? Any help would be appreciated if anyone can help. Many thanks in advance!
