Philadelphia is mural-crazy, covering every blank wall it can with murals – some commissioned and painted by professional artists, but many others the cheerful product of community pride. “Last year at this time the mural count was about 1,800. Now it is 1,900, which prompts the question, how many will be enough? Has mural-painting become a bureaucratic cottage industry? Has it become so important to the city’s tourist promotion that no one will ever recognize a practical limit?” – Philadelphia Inquirer
