There are lots of Cantu & Sons stamps on Horton Street (and indeed, everywhere in the neighborhood, as I’ve mentioned before) including this one on the east side of the street between Jerome and the northern dead end. Several just like this one are near the 1944 DPW stamp I previously featured.

What’s interesting about this one is the fact that Cantu & Sons apparently got a new style of stamp midway through 1987. Some 1987 stamps, and all 1988 stamps I have seen, just have “Cantu & Sons” and the date; other 1987 stamps, like this one, add “Cement Cont.” My guess is that this represents a name change. They may have dropped “Cement Contractors” as their business expanded beyond cement. Perhaps this was a pivotal moment on their way to becoming the Cantu Builders of today.

Update 3/11/21: I have discovered that Google maps has lied to me, and Horton is an Avenue, not a Street.
