Commissioned by NASA.
I love these for the same reason I love the NASA logo itself, the one known as "The Meatball." It's the goofy more-is-more graphic optimism of the early space age. (I don't love the alternative logo, known as "The Worm," which has fortunately been retired.)
Of course I'm biased, since my dad worked for NASA. He was at the research center now known as Glenn, formerly Lewis. They used to have "For the Benefit of All Mankind" spelled out in begonias in front of the building.
