“Butterfly’s Ball” is the title of this drawing, made in 1859 by Walter Crane (1845–1915). This artist, a printmaker, draughtsman, and designer, was a leading figure in the Arts and Craft movement. The watercolour is now in the collection of the Dept. Prints and Drawings, British Museum, London U.K. .
In the foreground a brownish snail is visible, with two large tentacles and of the smaller ones partly visible. The shell has a large aperture, three whorls and is sinistral. It is possible that this was done deliberately, as this drawing also served as a print study.
