Able Concrete and Cantu & Sons went in opposite directions: Able added “Concrete” to their stamp sometime between 1999 and 2004, while Cantu & Sons dropped it in 1987.
This stamp is on the south side of East Michigan Avenue between Magnolia and Hayford, in front of the McDaniels Insurance Agency.
This pleasantly old-fashioned little storefront was built in 1910. I don’t know for sure how long McDaniels has occupied the building, only that they don’t own it. Google Street View shows them moving in sometime between 2011 and 2015, preceded by Salon on Michigan. Based on city personal property tax records, I can see that other businesses that have occupied it include Afrikan Egyptian Bazaar (seemingly in the late 90s to early 2000s, though I don’t remember it at all) and some rando named Virgil Bernero. I’m just kidding, Virg, I voted for you. Based on the dates, he must have used it as his campaign office for the 2005 election.
