If you like to get up early in the summer, mornings around sunrise are great times for mural-hunting. Even on weekdays, the major streets can be quiet enough to slow down in your car and look around at the sides of buildings you've just passed. (And, on a bicycle, streets with skimpy shoulders — like the central parts of Speedway — don't feel as dangerous to me as they do with more traffic whizzing by a foot or two away.)
Here's a mural I spotted as I rolled by 4932 E. Speedway last August. I didn't write down the exact business name, but Google says it's the Elegant Junque Shop.
