I somehow misplaced the original scan I had of the Ripley piece I did as a private commission for an art collector a few years back. Fortunately, he had a scan made of the illustration for himself and he was kind enough to share it with me.
The collector took a print of the illustration the New York Comic- Con recently and this is what he wrote about meeting with Sigourney Weaver:
"Sigourney Weaver asked if I was the artist. I told her, "No, my friend Mark did it." She responded, "I've seen a lot of art of the character. A lot of it doesn't come out well. This one is beautiful." Then afterwards, as I was about to leave the room, a guy called me over to look at the print. He scrutinized it, then said, "Wow. This is great." It was Jim Simpson, Sigourney's husband".
