This magnet pictures an illustration by Warwick Goble from the early 1900s. It appeared in The Fairy Book by Dinah Maria Craik accompanying a Scandinavian tale, Adventures of John Dietrich.
The illustration pictures a cock at daybreak in a meadow of flowers as the little men prepare to retire into the glass door and back to their underground land.
Dinah Craik (1826-1887) was an English poet and novelist, also known by her maiden name as Miss Mulock.
English artist Warwick Goble (1862–1943) illustrated dozens of children's books and magazines, including fairy tale anthologies and such classics as Treasure Island and Kidnapped.
