In 2000 the USPS issued these 33 cents stamps. Over 120,000 entries were submitted by children from the U.S., Canada, China, Israel, and other countries when the U.S. Postal Service asked students to envision the 21st century. From 110 finalists, four winning illustrations were chosen to be featured on this set of stamps. The winners were Zachary Canter, age 9, of Hawaii; Ashley Young, age 11, of Utah; Morgan Hill, age 9, of New Jersey; and Sarah Lipsey, age 11, of Tennessee.
