...from the book, not the movie. I don't know why, but anytime The Unsharer gets brought up I just picture those body-less/face-less arms.

And whether we speculate on whether The Unsharer is a single person or multiple people, I still picture the Once-ler, only the Once-ler in the hey-day of his Thneed production output à la this picture. (I realize, now, that the illustrations were probably depicting multiple whatever-the-once-ler-is, but as a kid I imagined that the Once-ler could morph into anything, just like the Thneeds could)

Anyway GT, what do you picture when you think of The Unsharer?
