I agree with everything Paul and Scott said.
Scott S..... I think in general - the European cards were better taken care of than the cards from the states. There probably was a greater appreciation for cards at the time of issue (and for years after) in Europe. Since most of the vintage golf cards are from Europe - this would be why the golf cards have survived in better condition when compared to US baseball cards. This is just something I have heard from other collectors and tend to agree with.
edit:
I think a great place to start is the World Golf Hall of Fame website. Read up on the old legends of the game - get to know them - and then eBay search for cards. There will be cards for most all of them.
