puzzles - Rio Grande

For those who are interested in jigsaw puzzles, I just completed one titled "Rio Grande" by John Winfield. A wonderful little puzzle put out by Sunsout. (They have a website but do not sell retail over the web.)
It has a D&RGW F9 in the foreground with a 4-axle GM beside it. The horizon has what I think of as Denver out on the plains (so I'm guessing this is the old D&SL mainline). In the middle ground, a 4-unit freight is working its way uphill(?).
In the sky above "Denver" is written Rio Grande in speed lettering. Above the "rand" in Grande in the sky and clouds is a K-27, an articulated and one other steamer (sorry, I'm not too familiar with D&RGW SG stuff).
I do recommend it.
