History of the New York Subway tiles and typefaces
Squire J. Vickers was an architect and lead designer for the subway system from 1908 to 1942 and was responsible for 300 station designs. Here's a NYTimes article about Vickers.
The question remains: Who designed, manufactured and hand lettered the tiles? This short article in The New York Times identifies architects George C. Heins and Christopher Grant La Farge
From the article THE (MOSTLY) TRUE STORY OF HELVETICA AND THE NEW YORK CITY SUBWAY:
"For the IND Vickers also added a second set of modular tiles for the station names. These were integrated into the station walls rather than being attached to the platform columns. The lettering of these signs is in a spur serif style—common in 19th-century sign-painting manuals—that is reminiscent of social invitation typefaces such as Copperplate Gothic."
From Forgotten New York:
"Vickers also designed smaller, black and white directional signs pointing to the closest exits, with a simple arrow pointing in the direction the traveler should go. These signs featured a font quite like Copperplate, the font I use (along with Franklin Gothic) for FNY title cards. It wasn’t Copperplate, though; the font featured small, “vestigial” serifs much like Copperplate but it wasn’t quite the same. I wonder what the font name was."
I'm using a font editor called Glyphs to import the Illustrator paths and export to an Open Type Face.
