that's the famous North Park water tower in the background... it was built in 1924, held a million gallons of water, and was claimed to be the “largest elevated tank in the world” when constructed

the work on constructing the all-steel tower and tank began in 1923 by the Pittsburg-Des Moines Steel Company. The 52’3” tank is supported by 12 steel piers, each resting upon a concrete foundation set nine feet into the hardpan.
