Well, OK. That just proves he didn't need 70 to "forever less one day" in order to write it.
But the evidence is strongly on the side that he needed at least 50 years. I mean, did you see him writing Gatsby before the 1909 copyright act? No, you didn't, because before that, he'd have somewhere around 40 piddling years of copyright protection. But the 1909 act passes and sure enough, Gatsby comes out less than 15 years later.
If you have any sources about Fitzgerald's take on copyright terms I would love to read them, but without that you have absolutely no basis with which to say that there is "strong evidence" that he required more than 50 years.
I'll also point out that it's hard to write about the roaring '20s before the Copyright act of 1909.
Yep. It's almost as if such an argument would be too absurd to take seriously.
Through Copyright, All Things Are Possible!
Hail Copyright!
Is my sarcasm detector off? Or are you just a really bizarre troll?
