Art from Germany

This striking postcard came from Ingrid in Germany. She has written an elaborate description on the back, and unfortunately her handwriting is quite cursive and I cannot quite make out the exact details but I think this is a piece of wall art painted on the Berlin Wall, which divided friends and family and symbolised a life without freedom. Many people painted messages on the wall - images of hope and contemplation, sadness and joy, adorning both sides in what was probably the most unique open air-gallery in the world, showing the hopes and dreams of many mostly unknown people.
I guess that means that it was lost when the wall came down, but at least these picture remain to remind us of what was done.
