Want to get your original artwork in everyone’s wallet? The Mayor’s Office and San Francisco Public library are hosting an ImproveSF.com challenge, asking you to design new versions of San Francisco Public Library cards in honor of national Library Card month. Starting Sept 4 and continuing through Oct 5, children, teens and adults will have a chance to submit their original artwork for consideration.

Five winning designs will be featured on new San Francisco library cards issued in 2013. There are more than 400,000 San Francisco library cards in active circulation, with SF Public Library issuing about 60,000 new cards each year.
