“Joltin'” Joe Sinnott is universally lauded by Marvel Comics and the fan community. In his introduction to Tim Lasiuta’s Brush Strokes With Greatness: The Life & Art Of Joe Sinnott, Stan Lee wrote: “[P]encilers used to hurl all sorts of dire threats at me if I didn’t make certain that Joe, and only Joe, inked their pages. I knew I couldn’t satisfy everyone and I had to save the very most important strips for [him]. To most pencilers, having Joe Sinnott ink their artwork was tantamount to grabbing the brass ring.”
Sinnott has been praised for his smooth, unique ink-work by a wide array of pencilers, including Alex Saviuk. Sinnott is always asked by comicbook collectors and fans alike for autographs on prints, sketches, and comics from generations ago, knowing that his signature would only appreciate their value as time goes on.
