This stamp is on a driveway on the north side of East Michigan Avenue between Leslie and Horton. It’s what I call a ghost driveway; the house it belonged to was demolished sometime between 2008 and 2011, along with another one next door. It was one of those old houses-turned-businesses that line so much of the Avenue here. The city has an account for a business called “Digital Photo Magic” at this address, indicating delinquent taxes for 1999 and 2000, so they may have been here when this stamp was made. I can’t find much else about the history of the house except that in the 1950s and early ’60s it was home to a real estate agency called Brennan Realty Co.
