To promote their fine products, Zenith utilized signs that hung in their dealers stores.  I like the genuine feeling they add to my displays. Zenith also published ads in the most popular magazines like National Geographic, Saturday Evening Post, Time, Newsweek and issued product brochures.  Here are a few examples I have been able to gather.
