When we redid the bathroom in my 100 year old Baltimore house, we found some pretty rad stuff.
Old crumpled newspapers from the time of construction were shoved in the walls. These were interior walls, I think to assist with holding the plaster in the laths. I was able to salvage part of one page with a comic strip. You wouldn't have even thought the comic was much out-of-date either.
<even more off-topic> So at some point one of the prior owners decided to 'modernize' the bathroom and turn the original clawfoot tub into a modern recessed bath. They did this by buding a brick surround around it, covered with tiles. Weighed a TON. But underneath when we demished the surround, we saw planks of wood lying next to the tub. Turns out they weren't wood but dusty marble trim that originally surrounded the walls along the floor. Original charm from the original house! We had no idea the tub was even a clawfoot, much less there was marble trim.
No, this was about 7+ yrs ago. I should have it somewhere in storage though.
IIRC it showed a disheveled older man, with a big beard and dressed like a stereotypical 'hobo', eating some food out of a tin can and making some snarky comment which I don't remember. The drawing, in black and white, had a bit of feel like the older Mickey Mouse or Tom and Jerry style to it, but didn't seem too obviously out of date.
