People have been drawing on walls since ancient times and today many graffiti artists have crossed over into making a living off their art. Keith Haring was a famous artist who began his career drawing on advertising boards in the subway. His foundation has a fun website for kids (of all ages!) where you can play games (like Hangman) or draw your own graffiti. Sticking with the Detroit theme I have going, this week’s WW photo is of some cool graffiti on a wall downtown. See other Wordless Wednesday participants here.
