Anthony N.I posted this on the post war board, but since that side seems to be ignored.....
Of the set I collect (Great Moments) there are 70 cards that are possible to have been signed, if you include Campy.
As Rich stated, many of them are readily available, and as SGC does not authenticate autographs PSA is the only viable option. The cards resemble T3's, and IMO PSA's T3 holder is the best one they make.
The first 60 cards are pretty easy to find signed, a few will cost a bit more (Bunning can be tough, I had a problem with Frank Robinson for some reason, as well as Lasorda_ but the last 10 will get increasingly harder. Ashburn is by far the toughest, having been alive for a very short time after his card was issued. It will run about 3-4K if you can find one.
Some of the cards feature really nice artwork, with period outfield signage, great action, etc. A few are way off, and I think Koufax actually looks more like Drysdale.
I posted a bunch of my favorites on the post war thread.
edited to add apologies to Leon and others for a postwar post on the prewar side
