The late, great Don Newton's comic art for Batman is pretty well known, but here's an acrylics composition of his showing off a slightly different style! It's very evocative of early Year One Bats. I suspect that this was done in the years before Don started working at DC, since I've seen similar paintings showing Namor and the Alan Scott version of Green Lantern that he did in 1969 and 1970 for fanzines. The vast majority of Don's early work when he was primarily involved in comics as a fan illustrator rather than a professional has been sold off in auctions for a pretty penny nowadays. Fun fact: Don was a fanzine artist for years before finally finding employ at Charleston Comics in 1974, and the fact that he lived in Arizona, rather than in NYC where DC and Marvel were located, was one of the major issues preventing his employ. Nevertheless, he didn't give up, and eventually became a legend!
