So, would you call this a "mural"? It's not paint on a wall, but it is on a wall. I took the photo on October 9, 2011, at TRS Heating Cooling & Construction, 5645 South Country Club, just north of Drexel.
Jerry Peek's images are public-domain. For non-profit use, he'd appreciate a mention of his name and JerryPeek.com. For profit, please ask first from the TucsonArt.info contact form; give the title of the blog entry, which image, and what you'd like to do.
For full-size versions of these shrunken photos — for instance, to print in a magazine — Jerry has them.
(Jerry is a volunteer who loves to show you murals, and your kindness will help him go on.) Thanks for reading!
