I've glued the pieces together on a piece of MDF and mounted it on my layout.
In front of the building is my fleet of P&LE diesel engines. All MTH (SW-1500, 2x GP-7, GP38-2, and U28B) .
The name right now is letters printed on paper and attached to the building using double-sided tape. It follows the contour of the layers of brick. Someday (famous last words) I hope to spray paint the white on the bricks and use large decal letters. This font is close to the font used on the prototype but does not match exactly. I'll have to try to find out what font the P&LE used (maybe an NYC font?).
I didn't mention earlier but the glass block windows were printed using white PLA. They could be backlit.
The P&LE logo is available for 3D printing on Thingiverse:
