This advertisement for the Milwaukee line that ran through Seattle towards Mount Rainier National Park is a good example of the changing style that was taking place in advertising, specifically in regards to the National Parks. Published in a 1912 theater program, this ad demonstrates a newfound emphasis on imagery. Unlike the ad from the Tacoma Eastern Railroad, this ad features no huge blocks of text. Instead, beautiful imagery is the focus here and the text does little more than to inform the reader of just the basic information. Notice that Mt. Rainier itself is the selling point, not the activities that you could do on the slopes.
