When I saw this giant mirror where the u-bahn (subway) conductor looks to make sure it's safe to close the doors and pull away from the station, I couldn't resist taking a selfie . . . bundled up in the cold, appreciating the fleece-lined leggings.
I like the feel of an insert, but then knowing it is actually a mirror. And the leading lines that are suddenly disrupted by a photographer in the midst. Cool shot.
