i'm not a plastic bag: another one spotted in midtown

I spotted my third I'm NOT A Plastic bag, carried by a shopper in Midtown. I don't think she was on her way to buy groceries though.I am noticing one extreme drawback of carrying Anya Hindmarch's I'm NOT A Plastic bag as your everyday handbag (instead of as the eco-friendly cloth alternative to a plastic grocery store bag for which it was originally intended). The white canvas bag gets filthy!
