I believe it is that exact hallway/walkway. All details seem to line up, even colors.the lobby in the postcard looks like the one they used in the film, the Reform Club in London:

Looking closer I actually think it's the ground floor seen in the postcard, you can see the notice board and some weird wooden structure on the right (I added a new pic in my original post)I believe it is that exact hallway/walkway. All details seem to line up, even colors.
yeah, we’ve narrowed it down to the lobby used but I doubt we will find the right photo used. They probably had a production assistant or prop maker walk in, snap a photo, and walk out. It may never have been shared publicly. Maybe if someone on the RPF lives close to the place, they could go in with reference and try to shoot the exact angle.I actually think the photograph posted by Moviefreak is flipped and not of the actual corner, if you look at the way the text on the notice board is aligned right to left and you compare the paintings to this photograph, and also on the left you can see the stairs, while in the picture I posted it would be a mirror

( I actually think the door we're looking for is on the opposite side of the stairs)
