This black and white photo from the mid-1900's, released by the John F. Kennedy Presidential Library and Museum in Boston on Wednesday, March 28, 2012, shows Ernest Hemingway, second from right, and Gianfranco Ivancich, right, dining with an unidentified woman, left, wife Mary Hemingway, second from left, and Juan "Sinsky" Dunabeitia, center at Hemingway's villa Finca Vigia in San Francisco de Paula, Cuba. The museum made public on Wednesday a dozen previously unpublished letters Hemingway wrote to Ivancich. Experts say the letters demonstrate tenderness in Hemingway?s character that wasn?t necessarily part of his public persona. (AP Photo/John F. Kennedy Presidential Library and Museum)
