This tough-to-read stamp is on the west side of North Magnolia Avenue between Vine and Fernwood. I can be fairly confident that the last name is “West,” but what comes before that is illegible. It looks like two initials.
The only lead I have is a series of classified advertisements that ran in the Lansing State Journal in March and May of 1953: “CEMENT – And concrete work… Phone Dick Connick, 97392, or Dick West, 23050.” Searching for references to Dick West in the LSJ are stymied by the existence of a UPI correspondent by that name.
