Showcased here is an unpainted Mantis hardcopy. The piece is cast in a green urethane, commonly referred to as "dynacast". This material was prominently used for hardcopies during the mid-80's.
Hardcopies are produced using a silicone mold (this mold is created from the original wax figure sculpting). Once it is removed from the mold it may serve a number of purposes. It might remain unpainted and ultimately used to create the steel tooling for the figures. Extra hardcopies are also poured as a precaution, should something happen to the tooling master. These extras would remain unpainted as well. If a hardcopy is not destined for tooling or backup, then it will more than likely be handpainted for use in catalog photography, trade shows, or as a paintmaster. Most paintmasters for the Super Powers line are cast in milky white proto plastic (commonly referred to as internal first shots), but I have seen dynacast paintmasters.
This hardcopy is complete with the exception of a missing left hand. The detail on this hardcopy is incredible and like all hardcopies, it is slightly larger than the production version. This is true because resin is not susceptible to shrinkage like injection molded plastic. All hardcopies have removeable limbs, which are held onto the torso via metal dowels.
