Is that the "birthday" issue? That's gotta be a tough one.
My friend calls it the Jewish Superman variant
It was commissioned to Godfrey Bradman son's Bar Mizva. Mixed reports on its run but the most would be 200
At a show last year, I was working the CGC booth when an older guy comes up and asks whether I wanted to see something rare. He then pulls out a copy of the Superman Bradman issue.
As I know how pricey this book is, I immediately ask him whether he is going to submit the book. He replies sure and I start grabbing a CGC invoice. When I put it down in front of him, he says "is this for a signed copy?" at which point I was thinking "great - time to explain yet again that unwitnessed signatures cannot get SS labels".
I'm about halfway into my spiel about the differences between blue, green and yellow label books when he looks up at me at says "oh, I'm sorry for confusing you - my name's David Levin, I wrote this book, and I'm interested in submitting it for SS after I sign it".
So he signs it in front of me, we fill out the paperwork and as far as I know it's the only SS copy of that book out there.
Neat!
Great story.. Looks like you did him a Mitzvah! (pun intended)
