"Night" is based on an egg tempera on panel painting, done in 1963. "Night" is Tooker's first original print.
Walter Maibaum of Editions Press in San Francisco describes this process in the book "George Tooker," published by David Tunkel Gallery (ISBN:0-936680-00-8).
"...Mr. Tooker also completed his first Original Intaglio Print, "Sleepers." (Actually titled "Night," or the "The Dreamer") This edition was printed without any color. The artist achieved his 'complete image' through clever use of three dimensions. His work was embossed into paper with heavy pressure with an intaglio press.
The Artist executed a three-dimensional Bas-Relief image utilizing a combination of sculptors and dental tools. He carefully sculpted wax into the form....A metal mold was made from his wax, and it was from this mold that the edition was ultimately embossed (printed) on the intaglio press."
