Vegetarian Stamps by PETA

PETA has launched a limited-edition sheet of U.S. postage PhotoStampsTM featuring famous vegetarians throughout history. The VIPs featured on these unique postage sheets ditched meat from their diets either out of concern for their health, for the environment, or for animals—and our world would not be the same without their accomplishments. Although the individuals featured in this series seem very different at first glance, they are united in their respect for animals.
