Vintage Baseball watch fob questions

[aelefson]

Hi-
I recently purchased the baseball watch fob scanned below and I had some questions I was hoping this board might be able to assist with.
1. Any idea how old it is (appproximately)?
2. Is it a watch fob? I ask because any other watch fob I have seen is closer to the size of a pocket watch.
3. If it is not a watch fob, what is it?
I found it by emerging from a scrum of several like minded antiquers at approximately 6:30 in the morning at Brimfield's opening day yesterday. I stumbled across a dealer who had just thrown several boxes of sports memorabilia on the grass floor of his booth. The experience is one of the primary reasons I try to go to Brimfield at 4:00am every opening day. It is a lot of fun (and usually you get cool stuff).
Thanks in advance,
