This was taken in the studio of Peter Goodman in New York City. This is an unusual stereogram, actually a double exposure. The camera was locked down and between the 2 exposures I propped a matchbox behind the mirror seen on the right . By doing this the new angle of the mirror revealed and exposed a second painting reflected in the mirror. So only the image in the mirror has changed creating an eerie view of 2 overlapping paintings that were on the other side of the room.
