One the other end of the scale, the large size figures were incredibly detailed and hold up very well today. But they were more expensive, and the line faded away around the time Empire came out. Kenner probably only did a 12 inch Indiana Jones because they could reuse the Han Solo mold. Nevermind Indy's haircut looks nothing like Han's. ;)

Kenner was going to release a line of large size actions figures for ESB and even created some prototypes, but the line was eventually cancelled in favor of the smaller figures. Only IG-88 was produced and released.
