Share your information with thousands of Earth Day attendees! Place an ad in the Earth Day program, several thousand of which will be printed (on recycled paper) for attendees. Advertisers will be listed as contributors on the Earth Day website and in the Earth Day program. They may also provide their brochures and business cards for distribution at Earth Day Central at no additional cost. Sponsors receive an ad as part of their package. Ads are black & white. The deadline to submit your ad is April 16, 2012.
