In the Photos section of the Pendraken Forum there is a thread entitled Train and Plane Dioramas, featuring the many works of Carlos Briz (and it is pretty inspirational stuff as well). His latest offering features trains at the side of a river during the ACW. Both the Confederate and the Union diorama feature Peter Pig ships and the fort to enhance the riverside location. Well worth a look. He has also produced many WWI and II dioramas as well as some colonial and later C19th European wars subjects.
Thanks, Leman - looking good!
