Walking around New York City you’ll quickly see that not a spec of space is sacred. Everything, except maybe the squirrels, is open to advertising. The popular food carts have long had signs on them promoting Gyros, local business and even specialty food brands. Today I spied a vendor with two outrageous Home Depot umbrellas on his cart. You’ll have to go to 23rd and 5th, to see it. Boy, does it stand out.
