In 1970 (at age fourteen), I saved the magazine advertisement, below, about the first Earth Day.
At some point, I attached the ad to the white paper visible behind it, in order--as I recall--to frame it.
Part of the ad is obviously missing; it got torn decades ago.
The title originally read: "April 22 is Earth Day. The beginning of the end of pollution."
The
ad was from the Environmental Action Coalition of New York. The
group (which was active for many years) was originally created to oversee New York City's 1970 Earth Day events.
