What if the moon had a National Park we could all visit? We think the first one would be Tranquility Base National Park to commemorate the first moon landing. Fifty years ago on July 20th man first stepped on the moon. Let's celebrate this monumental effort of Apollo 11 with this "Special Edition" Tranquility Base NP sticker. Our Tranquility Base National Park sticker is 4 inches round, durable and weatherproof. The button is 2-1/4 inches and will look great on your pack or jacket. The sticker is made out of thick, durable vinyl with a UV laminate that protects your stickers from scratching, rain and sunlight. Get your Moon Geek on with FREE shipping on your sticker.
