There is an impression of "Under Sea Ballet" in the British Museum. In 1942 Hugo's wife, author Anais Nin, was looking for a publisher for her book "Under a Glass Bell." When she could not find one she and Hugo (Hugh Guiler) started Gemor Press with Hugo creating a series of copper engravings, printed in relief as illustrations. "Under Sea Ballet," was done in a format that could be used for the cover, but was not selected, the image "Under a Glass Bell" was finally decided upon.
