George Harrison Marks and Pamela Green sometimes dabbled with 3-d photography. The results of which can be seen in Intimate Studies of Beauty No.6. This pocket publication was published by A. Hallé Ltd of London and forms part of a series of at least seven books. Apparently no expense was spared to “combine first class photography, faultless printing and classic posing — all in harmony to capture every aspect of beauty in the female form” and all in 3-D for only 2’6, including spectacles. A bargain for sure!
