Check out this picture below of eBay auction # 280729229207.
I sent the eBay seller a message letting him know what he was selling and here was his response back:
"Thanks for your opinion. I bought it off of eBay after a PSA/DNA quick opinion, which noted it as likely genuine. The only discrepancy is the "k", which appears he was just rushed when he signed it. My autographs are not only subjected to quick opinion, but also message boards with tons of years of combined experience (sports collectors.net)

What are your opinions on this Koufax signature? IMHO it's horrible and not even close.
