Robert's signature looks as if it is applied with a marker on top of the paint, the winter scene picture below seems to have a similar signature.
Lee Fana Art Gallery
The listing says "circa 1980", and mine looks like it's from the same era.

I found the following five paintings listed under "Robert More" here: http://www.oil3d.com/search/node/robert%20more
I'm quite certain this is the same painter because the winter scene is so similar to the above painting.

"This very nice oil painting is done by Robert More .
The canvas measured from the back is 24x20.With the frame its 30 x28.It looks much more vivid then the picture shows."
The fame and mat look idential to the snow scene with cabin above.

Not my favorite, but that might be partially based on a poor photo and it being removed from stretcher.
