It's neat, alright; I'm thinking it was taken during the Enemy Aircraft Exhibition at RAE Farnborough in October 1945.
No, actually, it looks like it was taken in the USA, judging on the number on the Flettner Kolibri just visible behind the DB engine in the Bf 109G cowl. It's wearing FE-4613/T2-4613, which was Wk Nr 280023 and was taken to the USA aboard HMS Reaper. The machine was tested at Benedict Airport, Booth Corners, Pennsylvania.
This is also supported by the He 162, 'White 23', which is the NASM machine. It was at Freeman Field for a bit; was that where the photo was taken?
