Matt,

The Koufax signature on your card is somewhat tricky to guage and perhaps a bit ambiguous.

My first impression is that "Koufax" appears to be correct from some of my 1960's exemplars of him. The "S" in Sandy is not his typical S from this or any other time period. The signature, for sure, does not appear to be one that he took his time signing. Perhaps because it was rushed, this led to the Sandy portion of the sig just ending up a little sloppier than normal. If this is real, perhaps it was signed quickly over the railing or while he was walking.

After looking at the scan of your card and looking to my Koufax exemplar file, I was left not feeling 100% certain either way. I took the additional step of posing this question to my close friend Phil Paul who is a Koufax specialist. His response matched mine, that we're not 100% certain either way FWIW.

I wish that I could be more helpful, but perhaps some of the other people on the board can give you the answers that you are looking for.
