Transparent People Making Secrets
Malcolm Mlodoch, who worked at Rush Studios before Richard Rush died, provides some details on the construction of the Transparent Anatomical Mannequins (TAMs):
"TAM wasn't vacuum formed -- it was a two-piece epoxy cast. The front and back of the figure each were cast separately in two-piece molds; one half of the mold was the outer skin surface, the other half of the mold had a positive of the internal anatomy. The void between them would be filled with the epoxy."
"When cast into this mold each final clear epoxy half would be a solid piece, with the outer skin on the outside and the internal anatomy in negative on the inside of the half. When painted from the inside this anatomy appeared to be inside a clear outer skin. This was what really set the TAM apart from all of the other transparent women. Rush was able to make them a lot easier than the Valeda figure or the others with the vacuum-formed skin shell over the 3-D inner anatomy (a method Rush had tried on the transparent twins and other figures).
A semi-transparent man swimming was made for Jaques Cousteau. Rush also made a nine foot tall transparent man for Sai Baba, a mystic in India.
