@westcoastassist,
Cant thank the contributors to this post enough for dropping your thoughts and references to other works. Thank you all.
I spent a week in Warsaw with the heir chasing down the location of these six which were know to be in private possession. They were given back without fan fair or defense. The back story is utterly amazing how their ownership was passed on.
The letters between the ancestors and the museum, the aged legal paperwork... it's all mind blowing and new to me. What little I knew of WWII, this family's huge part the underground resistance, fall of communism - it spanned generations and is worthy of screenplays.
This is just one painting and I chose this forum to see what kind of assistance could be generated from a public forum - it's only been a day and it's opened our eyes to the possibilities. Two of the paintings are absolutely verified and the artists known. As we slowly reach out to experts we are trying hard to know as much about each work prior to contact them.
The paintings have already changed the family member's lives in so many ways but it's just a drop in the bucket compared to what is in store for them. It is a story so closely aligned to the Rosenthal's but the major difference is that this family is not wealthy - they once were, in Poland, prior to the invasion. A wealth built upon construction and heavy industry disappeared and lay in ruin... their few children that survived fled to the United States except for two teen cousins. Those boys stayed and fought in the underground resistance, spent time in a concentration camp... the story goes on like so many others of the time.
I am assisting, full time as it were, the daughter of one of those cousins. This gentleman eventually immigrated to the United States and became a scholar in the political sciences. His story, the story of the family before and during WWII, were hidden from this generation. His final months before his death he left notes to his daughter, hidden in cards and artwork she had made him when she was a child. The story unfolds and I am honored to play a small part in attempting to connect the background of these paintings with the incredible history of this family.
