Upper Playground in association with Fifty24SF and WALLSPACE SF has helped to organize the next large-scale mural for Barcelona artist and renown muralist, ARYZ.

Due to be finished this week, ARYZ has been hard at work since Friday, scaling the wall of a building located in the Tenderloin district.  Here are the latest work-in-progress photos revealing what ARYZ has been up to this weekend:
