I removed the last of the ancient wooden boards attached randomly to joists and walls in our basement and piled it all in the yard ready for disposal. A heap of split, splintered rusty-nailed junk caked in decades of paint and grime. So it stayed almost for a week, before Heather noticed some writing on one beneath the filth.
Naturally, it had to be saved: pulled from the pile, denailed, two lengthwise cracks woodglued, cut down to the interesting part, cleaned with detergent and oxalic acid, sealed and lacquered. Very proud of myself! I bet I could get $5 for it on Etsy.
Our find was probably the side of a wooden box that the house's original 1920s-era electrics were delivered in.
