[E. L. Moore's Background Building; J. R. Fisher collection]
This model was never the subject of a particular E. L. Moore article, but it appeared as a generic background building in a number of published photos.
You can see it in this photo from the HOJPOJ Mfg. Co. article.
It's definitely a rudimentary building without much three-dimensional wall detailing; however, the surface patterning is interesting and I guess that's one reason it pops-up as a background building in many photos.
The roof is quite simple and is merely black painted balsa.
But, like many other E. L. Moore buildings, the roof comes off. There's no interior detail, but there's a hole in the floor for a light.
