Not 100% sure it's 1:1, but there's a standee that was available. Out of production a while, however.
The real question is: What is full size?
The Illusive Concepts licensed version, along with all the recasts of it (strangely allowed to be offered here) are known to be small by somewhere between 10%-20%. It is also a re-sculpt and not a direct casting from the original.
Very interesting, I too thought it was a direct cast, at least the body section. The cast of Han's head that I used for mine was taken from an IC seems to be to scale for a human head if it were 10-20% bigger it would look to big in my opinion. Maybe Harrison had a big head? :lol Can you fill us in a little more on the IC?
IIRC, the original was molded for a version that was supplied to Planet Hollywood. A pull was made out of the mold that was used to make the PH version (after it sat around at ILm for a bunch of years) and it was given to IC for reference. But they did not use it directly. They re-sculpted it. Then molded that, added it to the master for the final version, which was then molded again and poorly reproduced.
So we are looking at, at least four chances for shrinkage on a 7 foot item. That's 2%-5% of shrinkage per casting or 8%-20%.
Look really closely at screen grabs of the face, you'll see the differences.
Interesting that the one at ILM has no control panels on it.
