"Requiem for Methuselah" gave a brief mention to a painter named Reginald Pollack, implying that he would become one of the most famous artists in history with his paintings known for centuries after his death. In the episode, Pollack art was in the collection of the immortal "Mr. Flint" who may have once lived as Pollack. I have a Reginald Pollack (a real painter who was active in Greenwhich Village and LA until his death in 2001), for sale. If you Wiki him, it will confirm that he was, in fact, the source of the source of this Star Trek reference. I don't know if there is any interest in his paintings in the Star Trek community, but I thought I would offer it there, first. My email is email@example.com.
