400
I scanned in another 50 pages, for a total of 400. I'm definitely getting close to the end, with about three more blocks that size.
The way things have been going, every milestone falls tantalizingly close to a much more interesting image. This one also happened to fall at the very end of a run of drawings on lined paper. I've found lines impossible to remove cleanly, so they have to stay.
