Got the card today My checked was cashed in May. So 4 month wait after that probably isn't bad. Very happy right now. Thank you all for the feedback

Sent the desired donation, baseball card and autograph requests to Nolan Ryan's foundation some time ago, after several weeks, the check was cashed but still waiting on the autograph.
Anyone have any experiences like this.
Thanks.

Sent an autograph request and baseball card to Jon Lieber on April 25, 2011 to 3060 Isle Of Palms Dr W. Mobile, AL. 36695-2576.
He responded in July.
Thanks to Lieber.

I got a response from this address in only 18 days. Great response

Congrats, I received Suppan's autograph through the mail this summer. It was a 50 day wait and he responded from the Kansas City Royal's address.
