Early March is art season in New York.

The world-famous Armory Show is right across the street.

Mame hopes a sign will bring art buyers.

Helpfully, she displays her art to passersby.

Coffee is only five cents here.

And thanks to her collaborator Chris Trela, it comes in a limited-edition cup commemorating the film "Guest of Cindy Sherman."

Only five cents, and a collectible cup, too?

Look! A customer!

Mame is selling these prints for about $1 each, but this customer is only getting coffee.

Aha! This customer is buying.

Finally, a small crowd.

Grand total:over 50 pieces sold. "Your prices are better, says one customer."

Until next year.

A tiny bit richer but highly caffeinated, Mame hops on a Vespa. The cart goes back to the garage in Queens.
