Duty Free Zone (1947?), Fun Size (1968)

[Sam Clements]

Newspaperarchive has "duty-free zone" referring to Mexico from 1920.  Also a
cite about Russia having a "fifty-first zone which is duty-free" from 1911.

>   We visited the "duty-free zone" of Colon.  It`s also called "DFZ" or
"free zone," or "EPZ" or "export processing zone."  This is the largest
duty-free zone in the Americas, and the second-largest in the world after
China (Hong Kong).
>    I was told that it began in 1947.  OED doesn't have "duty-free zone,"
and OED's other "duty-free" definitions also appear to be way off.
