I compared this to a 1945 signature which i got from his old golf pro. Frank had several different signatures over the years and I do see some similarities. The F is very close as is the T. My signature shows a joining of the K to the S and the loop in the S is a lot smaller than the top of the S. Mine is dedicated to Jerry (Who was actually Rosalind Russells). Where i see a clear difference is in the dedication, The word 'To' is completely different, But that's not to say he perhaps chose to do it 'His Way' at the time.
