Mark Fleming just sent me photos of new Joe Pagac murals on the wall of Congress Street just west of Playground. These are on the vacant space next door, 272-274 East Congress:
The EXIF data in the photos says that Mark took them on April 7th.
A big thanks to you, Mark, for sending photos of all the new murals you find. (We have a lot of new readers here, I think. FYI, folks, I'm glad to get photos from you, too. There's no way I can keep track of all the new murals in Tucson myself!)
Update (September 9, 2013): There are new murals at this same spot.
