AMERICA'S ROOTS

“Be part of history,” proclaims the copy on one ad. “Choose our national tree,” says another, explaining that the appointed tree will symbolize all of Amer ica’s trees.

Mount Vernon, the home of George Washington, is pictured in one ad surrounded by trees planted by old George himself. A leafy Central Park-like scene is shown in another with a quote from Teddy Roosevelt expounding on the importance of trees to the U.S.

The ads, part of a PSA series promoting The National Arbor Day Foundation’s national-tree voting drive, urge Americans to choose at the foundation’s Web site, arborday.
