Hit the above link to go Olson Displays and see this new accessory for Prewar layouts. This is absolutely brilliant. This is a prewar backdrop/mountain. It is actually only 4 inches thick and it is made to be place or mounted onto a layout to give that "wide open", mountainous look in a prewar style. This is something Lionel coulda, shoulda, woulda done but didn't. Thanksfully, Olson Displays did it and really whacked the ball out of the park.
