back in the early 70's a notice was posted out front of an old house in our neighborhood that'd sat vacant for decades it was going to be torn down the following week by the new owner, an area spec house builder.
Evening before demo let mysef in to take a gander, always liked old houses. Up in the attic noticed what looked like a plastered over door opening on one wall, gave it a kick and it buckled inward, revealing a small room.
In it were old clothes, a tool box with Proto wrenches in it, a couple of boxes of books with leather covers, some from the late 1800's, a whole lot of assorted junk, and a small leather box.
Inside the box were old Navajo silver and turquoise pieces, gold and silver rings, opal and amber stickpins, a half dozen gold and silver coins from the 1800's, and a dozen other goodies. The books, tools and leather box went home with me, ended up giving away all the contents of the leather box over the following decades to family and friends for birthdays, Xmas, anniversaries, etc.
By the end of the next day, what had been the house was now just a pile of rubble being scooped into 10 yard boxes.
