Don't you love when you find a piece of work from one of your favorite artists that you seemingly thought you knew everything about, yet have never seen before? This just happened to me with Kay Nielsen, a master from the Golden Age of Illustration. I've been scouring all my books about him, but alas! have found nothing. It came from a Tumblr, so there's even less evidence there..
Can anyone tell me which story this glorious illustration belongs to?
