This wall is on the west side of the building at 1016 W. St Marys. It's along the narrow driveway, so it's easy to miss — the first time!
At the bottom right of the mural is Ernie & Dora Basurta, 1947. I spoke with a man nearby, and he said that the building is still in the Basurta family, but he didn't have more details. I'm hoping to re-check murals around town and see if I can find more information... so I'll post an update here if I learn more about this one. (As always, if you know the story, please add it in a comment below or send me an email message.)
