Here's a fun vintage OUR EARTH pin.  Featuring the earth on a yellow background.  Earth is holding up 2 fingers on each hand- looks like PEACE sign, but since it only has 4 fingers on one side...  It is older, but not certain of the age.  Perfect for your pin collection!  Fair- Good Used Condition with 2 small rust/corrosion spots on the back of pin but no other damage found.  Back is gold toned metal.  Post looks fine and a clip/holder thing is present.  About 1 inch tall.
Please email with any questions.  Thanks!
