Picture of the movable pyramid prototype

The picture shows you my second Hellraiser Box, it is the prototype of the movable pyramid configuration.
I have made them in 1989 and lost it together with my first movable star configuration in the year 2000 near
St.Louis/Missouri. The dimension of the box was approx 4x4x4 inches and the panel design handpainted with goldpaint.
This picture is the only one which exist.
