Watercolor painting "Gengenbach" in 1942 Germany signed Greinke (?)

Original painting done in watercolor (and mixed media) on heavy weight paper representing a view of gengenbach in germany signed (perhaps by hans greinke - 1891-1960 - to be confirmed). Very beautiful workmanship and state of conservation, a beautiful testimony to the atmosphere of the time. Sheet size: 19.5/29 cm.
