I've always loved cross sections. I used to look at David Macauley's series on building historic architecture all the time as a kid. Every book would show someone sitting on that era's version of a toilet.
I decided to forego that tradition for this nursery rhyme. With a queen in the parlor, a king in the counting house, the knave could very well have been in the john, but I'll leave that to your imagination.
Influences for this piece also came from 'The Bears' Famous Invasion of Sicily', Alistair Graham's 'Full Moon Soup' and Eyvind Earle's backgrounds for Sleeping Beauty.
