@Gala,
The German soldier that they think painted the majority of them came back in 2003 for a visit.
He was captured in North Africa in 1943, so he would have come here almost immediately after capture.
The reason they arent sure who painted all of them is because one man would have had to painted almost continually since his arrival.
Either way, they are fantastic paintings, and the photo's dont do them justice.
They are much brighter in color when viewed in person.
