Yes, yes, I know, another Cantu & Son(s). But this one is notable for being the most recent one I have found. It’s actually a pair of them, on the north side of Prospect Street just west of Fairview.

The eastern stamp.

The style is the same as the ubiquitous 1987-88 stamps except for the handwritten date.
