Browsing ebay for interesting things and purchased this WWII German POW letter that was written in the Papago Park POW camp here in Phoenix.
If you don't know the story of the camp, there was a "Great Escape" from there in December of 1944.
His rank and name is Obergefreiter Rudolph Yahnke.
Some more info was that Miss ("Fräulein") Liselotte Kröger lived in the apartment of ("bei") Gretel Wilkens, road "General Litzmannstraße" No 110 III. This street name was existent only during 1933 - 45 according to Wikipedia. Before 1933 the street was named "Kleine Gärtnerstraße", after war it has been named "Stresemannstraße".
I had it partially translated and as follows,
"February 8, 1945
Dear Lotti,
Today at your 24th birthday my thoughts have swum to you as so many times before and they only wish you the good and a further long and lucky life. For your lovely regards you transmitted to me by ???? [I can't recognize the name] many thanks. With greeting once again, also to your mother and Hanni,
Rudi"
Pretty cool owning a piece of history from there.
