Sign painters traditionally had their own names for the letter styles they used.
Egyptian, as I recall, was a catch-all term and had nothing to do with Egypt or the middle east.
Gothic too, was simply a generic reference to a straight, nonserifed letter. Every sign painter learned a "plain gothic," with slight variations. It was a workhorse, used all the time. It was not based on a typestyle, and it certainly wasn't created from a "font" which was the name for a collection of type. Fonts were made of metal and found only in printeries. The word
font was never used as a synonym for letter style, or typestyle.
* Sign painters called their letter styles
alphabets. The word
font was never heard in a sign shop, as is evidenced by the sign industry literature of pre-computer years. Even in print shops, the word always referenced metal type collections purchased from font foundries.
Font never referred to the style of a letter. A font was what a printer used to print typestyles on paper. As author and typographer Carolina DeBartolo said on Quora a few years ago, "A font is what you use, a typestyle is what you see."

Another point: a sign painter's alphabets were generally not slavish imitations of printer's typestyles, but were developed on their own, though occasionally an architect would specify a typestyle, requiring a sign painter to use it. Obviously, many of the sign alphabets were
inspired by typestyles. But most sign makers knew that many typestyles do not function well at large sizes. So, they didn't copy them, or modified them if they did. The sign painter's world and the printer's world did not overlap much. But today, a sign often looks like "print." A sign covered in Times Roman, for example, looks weak, anemic, with way too much whiteness. It looks more like a page than a sign. Times Roman was designed for newspaper-size print, not for signs. Its lightness actually benefitted from cheap newsprint (because of dot gain). But on signs, as viewing distance increases, the thin strokes of this typestyle tend to disappear, leaving visible only a bunch of meaningless vertical strokes. Even the bold versions have this problem. Try overlaying Times Bold over other versions of Times. You'll find the thin strokes don't change much, if at all. So, using the bold version does not solve the problem of the skinny strokes. You can solve the problem by thickening the thin strokes, which was easily done when brush lettering. But not so easy to do from a keyboard. The real solution is to not use Times Roman on sign work, or to use it only rarely.
As I was coming up in the trade in the 70s, sign painter's gothic, or egyptian, if you will, was used far more than any other alphabet. It was used everywhere and on everything. A good journeyman could chew through large quantities of single-stroke gothic with consistency and speed. You could often identify a sign painter by looking at his gothic, though a sign painter's casual styles were even more identifying. And in spite of the fact that plain gothic was used far more than any other letter style, I don't remember anyone in the trade ever complaining about it. So it is ironic, baffling even, for me to hear someone advise not using a letter style today because it's "overused." It seems as silly as saying, "Don't use red." Because isn't red overused? Almost every customer requests red because it "stands out." So, how is their red lettering going to stand out from all the other red lettering?
I remember an old sign painter once telling me he used basically six letter styles for everything. Obviously, the six letter styles were "overused." I'll bet he used the same coffee cup every morning, too. He probably overused everything.

*I realize that language is like a living, breathing animal. Words evolve and change in meaning and usage. But it helps to at least know how words were used originally in our industry, as well as in the print industry. Especially so as the lines between the two continue to blur. It helps clear up things that are otherwise confusing. For example, in the US, a font is protected by copyright while a typestyle is not. How could this be if they are the same, or if one is just a subdivision of the other? A font is no longer made of metal, of course, but composed of digital code. The US Copyright Office protects a font as a computer program (as long as it is human-written digital code), a "work of authorship." But the
design of the letter forms, the typestyle, has never been protected in the US.
