Akzidenz as porcelain enamel as metal signage, from the Canarsie subway stop in Brooklyn. There’s a lesson here. See how much better that looks than all the new black signs with sticker letters? See how much better it looks than cheap vinyl banners? Think about that when you design a sign. Finding people who know how to do great work with great materials is worth it. If it isn’t torn down, this sign will still look great after the current generation of crappy signs are falling apart and barely readable. Do your clients a favor and spec something great.
