I had to scoot and shimmy on my belly under an old oak staircase to add a 3 way light switch going to the 2nd story. Amongst all the coal dust I found a page from an old newspaper under the bottom landing pad. The Detroit News, dated 1923! It didn't look too bad for being 92 years old. Dresses for $13 back then. I wondered how old that oak staircase was; now I know it must be at least 92 years old.
