Sliding Glass Doors Covered From Floor to Ceiling With Handprints

The drummer's room was covered in tiny hand prints on sliding glass doors. A closer examination revealed that they were on both the inside and outside of the glass. If you imagine a handprint on a piece of paper, it would be at a forty five degree angle to the line of your vision - but not quite on the same plane as the glass. You could sort of compress your fingers and thumb to get those prints on the glass,. The whole ridge that runs across the top of your palms, where your fingers start is not replicated in that angled print.
