Denver Clayton Lemaster, AKA "Denny"
I bought 17 Astros cards from the 1970 set recently and this card was signed (there was another card that was also signed, which will be posted soon).
I love the '70 set and have been trying to complete one (the entire set, not just the Astros). Very simple, with a nice gray front and a blue and yellow back. I was glad to get another card from this set with a sig...even though it's a bit messy. Maybe I'll send Denny a card to replace this one.
