I came across a great site, TypArchive
totally by accident yesterday and what a joy! It's a collection of found type and signage, focusing mainly on hand-painted signage from around the world but also includes quite a lot of auto type and neon.
The idea, "is to amass a comprehensive global collection of a high-quality images and produce hard-copy volumes"
. I hope it works out - that would be one cool reference book!
If signage is your thing, chances are you'll find this
rather interesting too.Images copyright the individual photographers. All from TypArchive.
