Rod Gilbert c/o New York Rangers - 35 days - 0.5/1
Mr. Gilbert didn't sign my card (a 1968-69 O-Pee-Chee card), but he sent it back and he added a signed (and personalized) 3.375" X 8.5" Rangers Alumni card. I'm happy with it, even though those kinds of odd-sized cards are a pain to store!
Doug Gilmour c/o Kingston Frontenacs - 13 days - 3/3
Mr. Gilmour also signed a 3rd card, but he signed it with a dry erase marker, so I was able to remove the autograph with only a dry tissue. I didn't care much about the 3rd card anyway, so I'm happy with the 2 cards above! :o)
