The closest I could come to a dragon was this wonderful botanical image, The Dragon Arum, from New illustration of the sexual system of Carolus von Linnaeus . . ., 1807, by Robert John Thornton.
After some browsing on Galaxy of Images I finally tried searching for "monsters" and found what I was looking for: "In the Clutches of the Monster," by Joseph Ferdinand Keppler, A Selection of Cartoons from Puck by Joseph Keppler, 1893.
Published in "Puck" May 28, 1890. The Louisiana lottery was among the most corrupt public lotteries in the United States, drawing much criticism and prosecution. This cartoon appeared at a time when Louisiana was attempting to recover from this disgrace, an attempt that was only partially successful. While the original agent of the lottery was dead, his successors' advertisements could still be found in print promoting the scheme for everyone to read, with the exception of the United States District Attorney.
Next year, maybe Jules Verne?
Happy Sea Monster Day!
