There are a lot of UPA cartoons on YouTube; I had never seen Christopher Crumpet (1953), another story drawn in a pseudo-simple style reminiscent of Edward Lear with a largely nonsensical tale by T. Hee and Robert Cannon. The cartoon also reminds me of the earliest animation sequences, which very often started with a hand drawing the characters (in this case the hand is also animated, though in a very different style).
