mirror, mirror on the wall

i think marburg is the only town that has an elevator to go up the hill the old town is built upon. actually we have 3 elevators (although one is part of a shop that has one part of the building on the base of the hill and another part up). so no one has to use those steep stairs going up. normally i avoid the elevator and walk up, but this morning i came from the library and was carrying really heavy books, so i allowed myself the luxury of being "carried" to the city. this is the wall next to the elevator...
