The only major differences between the 2 Stauffenberg images is the contrast, brightness and sharpness.
By simply adding more mid-range shadow to the first pic you begin to approximate the look of the second. Most of the shadows fall where they appear on the second image, with 2 major exceptions: the ear & the uniform decorations. There is no way for those elements to fall in shadow without being targeted independently as they catch most of the highlights in the first picture- more than the nose & forehead. That variation cannot be recreated by either brightening the first image or darkening the second. (But it might be recreated by photographing a photograph repeatedly over 50+ years). Also, in the second image there is a reduction in the harsh black outlines of facial features (look at the lips). Again, this is possible to do with simple levels manipulation, minor blurring or the degradation that comes from an image being reproduced countless times.
In other words, without knowing the original source for the 2 separate images most of the differences (including minor variations in width & angle) can be explained by possible differences in reproduction.
Unfortunately, Lord Xenu probably can't be blamed in this case.
