Playing with the contrast, gamma, etc., the first part of the signature looks like "abbe". I can't make out the rest. It's on the base of the right hand tree, in the lower right hand corner.
I just don't see it. Can you post what you're seeing? It was rare for concept art to be signed in an obvious way, so this would make the painting even more interesting...
Now that you mention it, I think the flowers tend to hide the signature. Here's the best I could do in a fixed photo. Hopefully, it shows where to look:
Did the FWRR engineers have to deal with unattended small kids on the ROW?
Yes. There were many areas on the line that had no fencing to stop kids from playing on the tracks. The only known injury, though, was when a girl rode her bike into the engine. She wasn't seriously hurt, but it provided yet another reason to shut down the line.
Yeah. As idyllic as the painting is, in reality, kids would be squishing pennies, playing chicken w/ the train, etc.
