I've learned over the years to comb through the plaster during demo cause you just never know what might have been lurking in the wall. These finds are not from the construction period. The pamphlet was slipped through the slats while doing a plaster repair on the stairs going to the third floor. The bottle and match book were in the ceiling. The floorboards above were removed at some point to run a circuit, so guessing that's when they made their way in the ceiling.
