This is Hemingway with a bull in the Summer of 1927. The photo was taken outside of Pamplona, Spain, a town that was recommended to Hemingway by Gertrude Stein. It is in Northern Spain, just South of the French border. The famous "running of the bulls" is held here every year during the Festival of San Fermin.
Pamplona and Hemingway's vacations there were the setting and inspiration for his first novel, "The Sun Also Rises."
