I decided to purchase The Complete Short Stories of Ernest Hemingway : The Finca Vigia Edition
published by Simon & Schuster in the US. It includes "The First Fourty-Nine" plus 21 other stories. Finca Vigia (Lookout Farm) was his home in San Francisco de Paula, Cuba where he lived on and off for 2 decades. It has a very short foreword by his sons. Wikipedia has a great synopsis about this collection.
