Actually, the crop marks are the long lines to tell where to trim.
The surveyor symbols in your example are called “registration marks” and are used to align overlays (the way we did things in the old days for what we called “process jobs” — 4 clear acetate overlays to get full color).
I used to own an ad agency and we did all that kind of stuff. Pica poles, Xacto knives, wax and screens (I think I still have a pica pole around here somewhere...). Manual kerning... wow, now that I look at what you can do with MS Word and Photoshop I am amazed we were able to produce anything at all. If you were to go back to our shop then, it would be like vising Fred Flinstone...
