2-Up Sculpt
Hasbro created many different toy lines and their internal staff could not sculpt everything. So while some sculpts were created in-house, most of the G.I.Joe: A Real American Hero sculpts were created by external contract artists. Bill Merklein was one of Hasbro's most prolific contract sculptors. Figure sculpts were made using the artists' medium of choice. Some used 2-part epoxy, while others used wax or clay. Bill prefers plumber's seal epoxy. The right lower leg was duplicated, so the left lower leg is a placeholder. This sculpt was personally photographed by Bill to document his work before sending the sculpt in to Hasbro. This photo is courtesy of Bill Merklein.
2-Up Paintmaster
2-Up resin hard copies were hand painted and used as a final color reference. At least two of these "paintmasters" would be made. One would be sent overseas to the factory, for reference as they created the final paint masks. One would be kept at Hasbro for reference and cataloging. This photo is courtesy of Andrew Felsburg.
