I have one from the 1970's (at least that's what I was told). Although the "Yankees" script is nice looking, the jacket itself has no real style. Your's puts it to shame, so I hope you don't mind me sharing it here.
It's not the best picture, but the only one I have on my computer now.
Searching Google images, I found one just like this from a Legendary auction in 2002. But their write-up says it's from the 1940's. I don't know.
