I have previously written about Lansing-based construction company Christman. This stamp is found on the north side of West Washtenaw Street between Walnut and Pine – outside Constitution Hall – and what makes it interesting is two things. First, both of the sets of Christman stamps I’d found before were in the greater Frandor metropolitan area and had dates in the 1950s or 60s.
Second, “constructors”? I guess they wanted to set themselves apart from all the boring contractors who go with the tried and true “construction” in their name.
