I am surprised that Disney has not yet tried a limited edition Walt Disney's Animated Classics collection with every animated feature to date. I could see such a collection easily selling for $1500 - $2000 amongst fans.
Actually I believe Home on the Range was hand drawn as a last-ditch attempt at the medium.
Yes, but only as a first step. The drawings were inked, painted and put together as a film using computers. Now the hand drawings themselves are not even done on paper, but directly in the computer through graphics tablets.
