If it is him, the flash must have really lit up the exposure as what should be an Iron cross medal looks washed out. It’s shaped right, but the black that should be in the middle isn’t there, though it’s possible that the black is enamel and glossy and just happened to flash. There are three medals in the right place low down on his side.
Two rows of ribbons.
Collar tab looks like oak leaf strip with a little curve to it Goering has the same tab in one of his pics, but I don’t recall if Hitler ever wore tabs on his collar, my impression is that he usually didn’t.
There’s enough detail there someone in the know should be able to confirm who it isn’t, if not who it is.
Medal looks like it’s all silver with numerous projections rather than four, so definitely not an iron cross...therefore not Hitler. So I’d go with the JPost id of Ribbentrop, if anyone knows they would.
