The Secret of the Underground Room by John Bellairs was published in 1990 by Dial Books for Young Readers. Edward Gorey created the dust jacket artwork for this title. This beautifully crafted painting was not included in the Bellairs offerings which Mr. Gorey sold through The Gotham Book Mart. I do not know what became of this work. This is the only book in the Bellairs series without a frontis illustration.
This is one of Mr. Gorey's disjointed dust jacket covers where the image from the rear panel does not flow smoothly into the front. The outdoor scene on the back makes an abrupt change at the edge of the book's spine, with the front cover showing "the underground room". Even so, the front cover portion is one of my favorite paintings created for this book series. The masterful work has only hints of colors, but the mood evoked by the tones fits the story perfectly. Edward Gorey is quoted as saying he painted in "mushroom colors", and this is a perfect example.
