If Mike Brady had designed water towers or water tanks, I imagine they’d have looked like this!
These are pages from a 1965 promotional book from the Committee of Steel Plate Producers, American Iron and Steel Institute, obviously to introduce industrial designers and engineers to the coolness and versatility of steel plate for water storage products. (This copy was missing the middle-section pages.)
We love the 60s-era illustrations depicting that happy time when balloon-festooned children always strolled hand-in-hand with their parents. Below is a small sampling; the entire booklet can be seen on my Flickr site by clicking any of the pictures below.
