"Ancient Order of the Deep" card that recognizes, presumably, in a humorous way a military person who has crossed the equator..... In 1958 abord the Uss Mount McKinley. The following is a little info about the ship. Card was laminated and is curved. It will flatten for storage if you wish.

USS Mount McKinley (AGC-7/LCC-7) was the lead ship of the Mount McKinley class of amphibious force command ships. She was named after the highest mountain in North America. She was designed as an amphibious force flagship, a floating command post with advanced communications equipment and extensive combat information spaces to be used by the amphibious forces commander and landing force commander during large-scale operations
