Nice job. I filled in some of the damaged areas of the painting by copying form other parts, then replaced the outer graphics. Not quite as authentic, but it'll make a nice model. I printed the result on Alps photgraphic paper at the approximate size for O and HO scales. I've posted some photos of the O scale print (one backlit, the other lit from the front), along with a larger image exported to .jpeg at:

I printed them out at a scale 30" diameter and 24" diameter (the photos are the 30" version). Anybody know the acutal size?
