"Images of Einstein: A Catalog" (AIP, 1979) says that the photograph was given by Einstein to Lotte Jacobi for reproduction rights, which would now be held by the University of New Hampshire. Permission to use this image must be requested from the Institute's Archives. Please contact firstname.lastname@example.org.
This print of Albert Einstein with his son, Hans Albert, is stamped on the verso: "Atelier Jacobi, Charlottenburg," which supports another source (G30, p. 38, in Images of Einstein: A Catalog (AIP, 1979)) featuring a similar image that locates the photograph in the Einstein Berlin home. The heavyweight paper to which the print is adhered bears the photographer's signature.
