The photograph of Greta Hering and Leon Haber

The photograph of Greta Hering, who is on the left, in a white dress (?), without a headdress, and Leon Haber, in a suit, with a tie and a handkerchief in his buttonhole, without facial hair; Leon Haber's hair is styled in the way he apparently styled it throughout his adult life - or at least that is what one may think from the preserved photographs: with a clear parting. The photo may have been taken during his engagement, although it is possible that it was taken after his marriage (the date of his marriage is unknown).All corners are cut to slant. On the back, there are traces of an album card to which the photo was once glued.
