MOGH pages, for the El Morocco and the New El Morocco.

You can see where New El Morocco chips were ordered in 1959. Then, in 1964, they ordered El Morocco chips again. Maybe another opening was planned, dropping the "New" part of the name?

That's just a possible theory, I have no evidence.

I didn't note the date of the magazine that this scan was from ...sorry! (December 12 fell on a Thursday in 1946, 1957, 1963)
