Just found them, posted below. Note the placement of the big poster I found in Solid’s sketchbook; at one point, it was hanging on the wall of what obviously looks like a music room somewhere, but found its way back into the sketchbooks. They must have taken it down — in preparation for leaving? What the hell happened?
There were twenty photos in all like this, hidden inside the directory folder on the original CD I got in the mail. I just didn’t think about looking for anything but the band name, at first.
