The image in question shows only the backs of the couple who some have since claimed are Queen Elizabeth II and Prince Philip.
Eisenstaedt did not caption the photographs from the occasion with the names of the guests in them.
If the pair were the British Queen and her husband, then celebrity photographer Eisenstaedt did not recognise them among the 4,000 other attendees, which seems unlikely.
On March 1, 2018 Twitter account @AfricaFactsZone tweeted the image with the caption: “Queen Elizabeth and Prince Philip bowing before Haile Selassie I of Ethiopia and his wife, Empress Menen Asfew.
“They are the only people they have ever bowed to as a royal couple.”
