According to this article, a new $40,000 mural in front of the Livermore library misspelled the names of "Einstein, Shakespeare, Vincent Van Gogh, Michelangelo and seven other historical figures."
It's going to cost them $6000 to fix. But the artist who created the mural isn't taking any of the blame. She says: "The people that are into humanities, and are into Blake's concept of enlightenment, they are not looking at the words. In their mind the words register correctly."
I'm no great speller myself, but if I was going to create a piece of artwork that the public would view--in front of a library no less--you bet I'd do some checking.
