Hans-Jürgen Kleinhammes born in 1923 in Lauenburg / Germany. In the early seventies, he was best known for his series of metaphysical landscapes and geometric silkscreen paintings. His pictures are not traded very high. It is still unclear if Hans-Jürgen Kleinhammes still alive.
A few weeks ago I found one of his previous posting works in a antique shop. More information about the german artist is not available.
