If you are in San Francisco and you get a chance to visit SFMOMA, I would highly recommend that you at least check out the incredible mural created by JR titled The Chronicles of San Francisco
Global City is a project by French artist Deck Two in which he freehand painted a wall using only an acrylic marker. The mural consists of landmarks from all over the globe, and that's where the name came from. Check it out!
