Christine and Justin, a couple from New York run this website gallery. “Each painting shows one thing we want, and sells for the price of the real item. So you can buy A Slice of Pepperoni for $3.00 or Dinner at Nobu for $152.00. When the painting sells we use the money to go out and buy that thing.” They cleverly apply the same concept to charitable items in the ‘needs for sale’ section such as toys for underprivileged children and food for Homeless Charities. (It's nice That).
