Flap Books for Adults

As a grandmother, I’m familiar with flap books, books where children get to lift flaps.  They are intended to make learning more fun and interactive, although there is debate as to whether they actually help toddlers learn new words (http://www.telegraph.co.uk/science/2016/09/14/lift-the-flap-books-may-stop-toddlers-learning-new-words-say-sci/). 

I hadn’t realized that such books had been around in the 16^th century until I came across an interesting article earlier this year:  “The Scandalous Flap Books of 16th-Century Venice”.  Apparently “flap books were a fun innovation in publishing, used for purposes both serious and satirical.”  As the article shows, these flap books were definitely intended for an adult audience:  http://www.atlasobscura.com/articles/sexy-venice-flapbooks?utm_source=twitter&utm_medium=atlas-page.
