I remember one of these in use at a crosswalk when I was in 1st or 2nd grade; someone from the school must've put these out in the middle of the road twice a day. That would have been mid to late '60's, small town Idaho. Later, probably the 6th or 7th grade, some of my school chums and I were tasked with cleaning out a storage thing, and there it was in a corner under a bunch of school-related detritus!
I wish now that I would have absconded with it! I doubt if anyone would have cared. It would probably fetch a pretty-penny at auction.
