Mike C (mac6185 on SCN) had a signing with Todd Helton a couple weeks ago. I had sent in my actual HOF Induction ceremony ticket from last year to the signing. It is stamped and cancelled at the post office induction weekend. I also sent in a plaque postcard that I had cancelled at the post office there as well. Both came back signed beautifully. I am excited to get these items signed from that magical trip to Cooperstown we did as a family last summer. I have a couple more to go on my ticket to complete it!
