I always found the Motorola TV ads from Taschen’s book All-American Ads of the 60s very unique. They feel so retro but still very futuristic at the same time and I love the way they portray the future in such a optimistic and bright way that was only possible in the mid 20th century.
The illustrations were drawn by Charles Schridde and the advertisements were often seen in Life Magazine and The Saturday Evening Post among other places in the early 1960s.
Sadly the first edition of the Taschen book is out of print and no longer available through their website. But you can surely get it through Amazon and other online shops.
