Here's an impressive door not only because of its imposing size, but because it was in use until mid-2015 hence it was in great shape when it was photographed:

This is in a 1916 building (245 North Superior Street, Toledo), originally the Northern National Bank, most recently a Key Bank branch which closed in July of 2015. The image is from the Toledo Blade and the article has many nice images of the bank's interior: http://www.toledoblade.com/gallery/A...uperior-Street.

The door is surprising. First, its size is comparable to that of US Federal Reserve banks and is quite large for a safe deposit vault. Second, it's clearly not 1916 vintage; I would guess 1930s or 1940s.

This looks like a York door though I can't begin to make out the builder's plate below the lower lock. On the upper right of the door is a black magnet, and a matching magnetic switch can just be seen inside the vault at the top of the frame. The floor of the vault matches the level outside the vault so the metal "bridge" provides a flat walkway (I assume the door's bottom is tapered like the top, only half of the bottom hinge is above floor level, and a larger version of this image clearly shows the innermost "box" does taper). Notice that part of the door has radiused corners and the rest has sharp corners. Even after this vault was retrofitted into the building there was more remodeling, the ceiling comes right down to the edge of the door frame's trim (which seems more modern than the door) and on the far right some kind of addition actually covers the corner of the trim.

The building itself is quite stylish:

Supposedly this will be converted into an events venue: http://www.toledoblade.com/business/...-building.html. I just hope they keep the HVAC running to deter rust and other problems.
