Young Palpatine and Darth Plagueis by Chris Trevas
I found this awesome artwork of a young Palpatine done by long time Star Wars artist Chris Trevas. It also features Darth Plagueis who was Palpatine's master featured in the novels who had arguably the greatest understanding of the Dark Side. From what little I've read, I would love to see a miniseries that highlighted the story of these two when this picture took place!
