My husband and I went to the Fox Theatre in Detroit last night to see one of my very favorite bands, Buggles, open for Seal. That’s why this entry is the very first one for a stamp located in the city of Detroit proper. In fact, I quickly discovered that the Foxtown area hosts a splendid menagerie of contractor stamps, and I had to quit pausing to take a photo of every one I saw or else we would be late for the show.

This particular stamp is on the north side of West Montcalm Street between Park and Clifford, next to a parking lot. I am guessing CES might be Corby Energy Services, which “provides construction, engineering and support services to utilities and related businesses throughout southeastern Michigan, Indiana and Ohio,” especially because this sidewalk block surrounds a utility hole cover.
