Just looked at my original Poser box. The manual has 6/95 on the back. The three floppy disks show a copyright of 1991-95 for Larry, and 1995 on the interface for Fractal Design. It required Mac OS 7 or greater. Fun to look through the manual again. The hands had five standard positions: taut, relaxed, fist, pointing and flat. But lots of the basics were there, and I remember how incredible it seemed at the time! Elisa/gryffnn
