Earth Day Posters from Years Gone By

I remember hearing about Earth Day in high school. Quite frankly, I thought it was a new thing, but apparently it’s been around since the 1970s and those are a couple of Earth Day posters from the past. There’s actually a whole bunch.

Some others feature an axe made with a tree branch, a collection of rare insects from the Pacific, an earth goddess, the Incredible Hulk and even the United States military. Although, I think Lewis Black’s dead Sponge Bob is more convincing.

Via Red Green and Blue.
