At Market St. and Duboce in San Francisco, thee's a trippy mural (shown at right - click on it for a larger version) all about the wonders of reading. I especially like the way the books blend into houses. As Joe pointed out, this mural has something in common with the South Side Goodwill mural that I blogged about back in February. That mural is also about books (and the weird faded bluish green people who reach for them). I think I like the style of the Pittsburgh mural, but the San Francisco mural is a lot more lyrical.
The books in the picture are: Chaim Potok, "The Chosen", Gabriel Garcia Marquez's "100 Years of Solitude", Maya Angelou's "I Know Why the Caged Bird Sings", "The Art Book", Cervantes' "Don Quixote", J.D. Salinger's "Catcher in the Rye", and Douglas Adams' "Hitchhiker's Guide to the Galaxy". An eclectic mix, but all good.
Now that you've put up with my hack criticism, for more information about the mural, try this page. It's evidently part of a larger "Bay Area Mural Awareness Month" program. That's one major difference between Pittsburgh and San Francisco's murals: SF murals are usually documented somewhere. I keep trying, but finding information about Pittsburgh murals is always a challenge. (Disclaimer: I only look for information about the web, so differing amounts of Internet penetration into various cities yadda yadda yadda blah blah blah, don't sue me.)
