Bernie, thank you for revisiting this topic. We purchased the Piotrowski book a few years ago. It is an excellent source. We've just returned from Chicago. However, we always fly through Milwaukee. The airport has one of the best used bookstores. At times in the past and even last week we have purchased signed Ander's books,some of the Melchior Wankowicz books and even a gut wrenching paperback gem titled "Od Caen do Wilhelmshafen" . This book has individual poems, photographs, drawings and stories by soldiers of the Polish 1st Armored Division and was printed in Belgium in 1945. You have a valuable resource close to you. You probably know about this bookstore but I thought I'd mention it for anyone else living in the area. You honor your family by your research. We are doing the same for our children and grandchildren.
Warm regards, Ewa D. - Nevada
