Hi,Only one from Oberstein has been reproduced dated July 11th 1928. It's obviously a photocopy of an original but here's a scan plus, I'm afraid, lots of see through due to very thin paper. Click image to enlarge.
I have been researching Oberstein's career for some time and notice that there is some correspondence from him included in the scrapbook. Could you provide details (or scans?)Thanks,
David Diehl
Excellent! Many thanks.
