This scene is on the side of the Magpies Pizza building, along 5th Street at 4th Avenue. (There's more farther along the wall, at the west end... but I'll let you find that on your own. Fourth Avenue is a great place to see murals.)
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!
