Diorama Portrays CPR Train   Seen putting the finishing touches to one of the striking dioramas in the Exhibit Room of the Chateau Frontenac, is the noted Canadian artist H. Leslie Smith. Dioramas are a form of paintings made up of a series of cut-out screens which give a third dimension and create a vivid illusion of realism. The diorama which Mr. Smith is seen completing portrays a modern CPR train roaring through the Rockies with Mount Eisenhower towering in the background.   Mr. Smith who was engaged to touch up a number of the dioramas in the exhibit and to execute new ones, is one of the group of outstanding Canadian artists who worked under the direction of James Crockart, A.R.C.A., when the diorama exhibit was first created in 1923. He is a professor at Sir George Williams College and one of the original students of the Montreal Ecole des Beaux Arts.   © 2005 William C. Slim       http://www.okthepk.ca
