letter from Alan Shepard to his parents, telling them about his new house, Ann's wedding, and, oh yeah, that he is being considered for the new "Man in Space" program. There's a letter from a slave named Vilet Lester, describing how she has been sold from one plantation owner to another. A letter from the product marketing manager for Campbell's Soup to Andy Warhol, expressing appreciation for Warhol's paintings and telling him to expect a shipment of a few cases of tomato soup. A sweet and gracious letter from David Bowie responding to his "very first American fan letter." Six different letters to FDR complaining about his decision to move Thanksgiving up a week (one asking if he could also change Sunday to Wednesday).
Go. Now. (But not if you have work to do!)
