I was given this from a family friend, and am trying to date it. From their other memorabilia, I know they were at the 'ring in 57, 59 and again in 64.
I've looked at pics of these on ebay, but haven't found anything that can help date it. I though maybe the stampings on the back could help.

Any ideas?
