Saw this staircase online, found a contact name, was allowed to photograph for 10 minutes, so I had to work fast! Turned out I had about 45 minutes as the contact person didn't kick me out. I didn't notice or think about moving the black mat at the bottom, but I probably shouldn't have started messing around with things when they were nice enough to let me in to shoot.
This was taken in one of the rooms of the Manitoba Legislative Building in Winnipeg, Canada. I had taken a tour of the building without a camera but thought this would make a good photograph. You can't get into this room without being on a tour, so I had to go back and do the tour again...with a camera.
