The lights are mounted under the roof, a single bulb in each. Most of the parts were scratch built from sheet metal. The brass ladders are from a Lionel Std. Gauge boxcar and the two support 'columns' are actually cutoffs from old electrical conduit. I love the postcard idea! I have a box of some vintage cards from a few local locations that no longer exist; may have to come up with some ideas to make a few more of these, haha.
