So, I was very intrigued by the little puzzle going on at the World’s Fair. I was quite dubious that I would be able to crack it, but I’d like to propose a theory that may be atleast partially correct. If not, there’s a lot of good coincidences.
Unifying theme? Things that occured in 1962.
The fish: In 1962 the US Toro (which is a name used for cowfish) made it’s 11,000th dive while off Long Island
The cow: The 1962 Nobel Prize in Chemistry was to John Cowdry Kendrew
Elvis: The movie depicted the Seattle World Fair which occured in 1962
The novel exerpt: The child suffered from polio—the vaccine for polio was discovered in 1962
The blackbirds: The first flight of the SR-71 Blackbird’s predecessor (A-12 Oxcart) occured in 1962
Just a guess. 🙂
