NYC Street Surprise for Photographer Martha Cooper on her 70th | What's new in Visual Communication? |

The famed Houston Street Wall was the site of a sidewalk surprise birthday party Saturday for photographer Martha Cooper, who was planning to stop by for what she thought would be a new mural shoot. The world famous graffiti photographer had no idea that artists How and Nosm had begun masking the letters of her nickname out of their mural at 7 a.m. to create a larger-than-life birthday card for her.
