Here an odd item I found at a local antique store. It's a wooden block with an engraved metal stamp attached that looks like it was hand drawn. The photo shows the front and back on top. The bottom pic is the front photo flipped so you can see what it would look like if the stamp were used. There is a hand drawn picture of a log cabin with a charged electric line and a woman wearing headphones seated on the top line apparently talking into a radio microphone. It measures 4" x 2-7/8" x 7/8". It reads, "We Are 1 High Voltage Individual/73/FROM/DORIS/Campbell/425/E. MAIN ST./SpenceR, MASS./01562." The reverse of the wood block identifies that it's from "HOUSE LANE & RIDGE AVE./PHILA. 29, PENNA." and I'm guessing that the plywood was glued (?) sometime around "APRIL 66" and the engraving dates to 1973, but that's strictly conjecture on my part. I did a Google search for Ms. Campbell, and it came back that she and her late husband Colin hold/held FCC radio operator licenses. I don't know how the stamp came to be found in East Winthrop, Maine, but here it is. You can have this unique go-with for just $10 plus postage.
