The sign accompanying the H-1 engine. It reads

A Workhorse for America's Dreams

A million mysteries had to be solved if we were to get astronauts to the Moon and back with safety. H-1 engines like this one provided the power to get the job done. Eight of them were clustered in the first stage of the Saturn I and the Saturn IB. These were the launch vehicles for the early Apollo/Saturn program where the essential systems and maneuvers required for success were tested. They also launched crews for all of the Skylab missions and Apollo/Soyuz, the history-making rendezvous of America and the USSR in space.
