Autograph Note, signed ("Papa"), 11 April 1959, responding to student reader Frank Crowther's inquiry about A Farewell to Arms, and alluding to the celebrated Paris Review interview

Cuba, 1959. 10 lines in ink on the bottom of the letter to Hemingway, with the mailing envelope. 4to. Generally fine (address on envelope struck through for forwarding). 10 lines in ink on the bottom of the letter to Hemingway, with the mailing envelope. 4to. Nobel Laureate Ernest Heminway answers a young reader's long query about the indeterminate sex of the unborn child in A Farewell to Arms, and P.S. concernign a phrase that appeared at the end of George Plimpton's interview of Hemingway for the Paris Review.
Hemingway applies Occam's Razor and gets right to it: "Dear Frank, Not knowing sex of child they referred to it either way as you supposed. Thanks for the letter. Don't know of any good 2nd-hand shit detectors being on the market lately but your own seems to be working OK. Bets luck, Papa".
