In June of 1939, King George VI became the first reigning British monarch to visit the United States. The trip featured all the staples of a royal visit: a sight-seeing tour of Washington, a formal State Dinner, and a big bash at the British Embassy, of which Representative Charles J. Bell said, "It was sort of like our church socials in Missouri."

And towards the end of the trip, the Roosevelts invited the royals to Hyde Park for hot dogs. Here's what else was on the menu:
