 A series of amusing transformational scenes, Tricks of Naughty Boys, is a Lothar Megandorfer book. One of the most important figures in the history of movable books. He was active in Germany in the late 19th century. The book that I have pulled from the collection was published in 1899. It is in English. His books were produced in Germany as well as in London and New York. It works in the Venetian blind structure. So you have one image where a boy is doing something, and you can't quite tell if it's good or bad, but when you pull down the tab to see the transformed image, you see that he's thrown a ball and broken a window and shopkeepers running after him, something like that. So it's very humorous. A lot of the images would be very benign today in terms of Naughty Boys, but it gives you some insight into a certain time and place. We have a few other Megandorfer's, but the difference is that they are reproductions. Whereas this is an original from the time period, which is a big reason that I selected it.
