Ok, so lets talk about the gloves...
The picture was made at Mannerheim´s return visit to Germany in June of 1942.
He visited Hitler at the Wolfsschanze and drove afterwards to the Reichsjägerhof Rominten where he met Goering.
At the railway station both wore gloves. Goering´s gloves seem to be almost white:
As the gloves on the bench are not pale they have to belong to Mannerheim.
But where are the gloves of Goering?
The following picture depicts both men walking around in Rominten. Mannerheim carried his marshal´s baton that we miss on the picture of the bench.
No one carries a headgear or gloves. So we can assume that Goering put his gloves under his uniform cap.
Any more questions, Mr. attorney?
