I'm a big fan of this company. They do an EXCELLENT job. Below are the backdrop panels used on my PRR Panhandle 2.0.

Long wall west (behind Steubenville, OH) of the Ohio River
Also on the long wall - the Ohio River north of the railroad bridge as taken on the water.

Not many people or products get my ringing endorsement, but this company does!
