I'd dispute that by HCB's day that cameras were an uncommon novelty. Remember that Kodak had already become the industrial juggernaut it was before WW II, and it did so by putting cameras in the hands of common people - "you push the button, we'll do the rest". So photography wasn't a novelty anymore.
That's true but they were usually only brought out of the closet for a special event, a birthday, family get together or vacation.
When they made an appearance it was "special".
Cameras were like cake.
I couldn't think of anything witty to say so I left this blank.
