This is the N Scale Freight Station Billboard from Blair Line Signs.
Great looking laser-cut wood "Cutout" Billboard Signs are perfect for rooftop or roadside and fit popular modeling eras. Each sign is designed to be assembled quickly and easily in layers, which simplifies painting and produces a highly realistic 3-D appearance. This series of smaller signs is cut from specially imported ultra-thin plywood for a finer and more prototypical appearance.
This sign is based on a combination of several prototypes and is perfect for transition-era layouts. Located on or near the main freight station, it helped draw attention to the railroad's less-than-carload-lot freight service. Although this business was eventually taken over by truck and plane, some of these signs survive today. The sign comes with 30 different full-color railroad heralds for customizing, or use decals for your favorite line.
