That exclamation mark expresses my astonishment well: in all my many decades exploring the diverse typology of lost pet signs, this is the first, even if incomplete, found pet sign. Please note that it is unrelated to the underlying call for volunteers. I might liken the found pet sign to a sighting of the holy grail, a posited proof, or a fragment of the true cross. I searched the area for more complete signs, but the trail was cold. My estimate is that it takes months for such signs to reach such a fragmented state, and I have abandoned hope. Chicago.
