US currency was beautiful, once upon a time, when it sported images of animals and symbolic statuary, rather than deifying its citizen-rulers by putting presidents on the money as though they were kings. This 1901 $10 note (available on Wikimedia Commons in a 33.34MB, 6,454 × 5,784 JPEG!) is a case in point.
