During 2015, Street Art SF photographed over 1600 pieces of art on the streets of San Francisco and Oakland. They ranged from small stickers and stencils to graffiti characters and large murals and pieces. Almost all of the art shown was done in 2015. Major photo contributions were made by Graff Hunter, West by Midwest Photography and Nite Owl.
We looked at the number of likes and re-blogs on tumblr to determine which pieces were the most popular. Notably there were quite a few artists who were consistent heavy “hitters” but did not have art in top posts. The art is shown in alpha order.
