Original cover sketch deals for "The Reality Matrix" by John Dalmas

This is the second cover sketch I did for for "The Reality Matrix" by John Dalmas. This is a piece of original art, one of a kind, and when it is sold there is no other. The sketch is deals in gouache paint, a finely ground tempera paint that I used for most of my sketches. The sketch measures 7 inches by 4,25 inches, the same size as the printed paperback book cover. It is on a piece of illustration board measuring 10 inches by 7.5 inches.
