Of course I'm referring to "Fields Corner," not the "no tresspassing" sign.

The H&FJ link on Gotham's History relates the font to signage on buildings. Here is the word "CORNER" in Gotham Bold.

Their text starts with "Long before the emergence of a profession called 'graphic design,' there was signage. Up until the mid-twentieth century, the job of providing architectural lettering often fell to engineers or draftsmen, most of whom worked outside of the typographic tradition. "
