This is an actual certificate from such a celebration for a seaman, Norman C. Davis, from January 24,1921.

Prior to WWII, world travel was an adventure for most people and crossing the equator was an event of some importance. In the navies of the U.S. and Great Britain, crossing the equator for the first time was an event celebrated by a ritual known Neptunus Rex. It is performed to initiate sailors as they cross the equator for the first time. The ceremony most likely began as a mystic ritual centuries ago and has evolved into a boisterous initiation of novices in the US Navy -- Pollywogs becoming Shellbacks.

The Certificate reads:
