What happens to groceries at the White House in a Presidential transition?

The sudden death of President Franklin D. Roosevelt threw both the Truman and Roosevelt households into disarray. Eleanor Roosevelt had over 12 years of accumulated household goods to move from the White House to her home in Hyde Park, New York.

The White House Kitchen also contained enough food to feed the President, the First Lady, their staff, and any potential guests. Rather than move the food, Bess Truman bought most of it from Eleanor Roosevelt. 

In addition to this note from Eleanor, written on this day in 1945, the Truman Library has the check, signed by Bess and endorsed by Eleanor, for $100.26.
