One of my favorite sites for inspiration is Grain Edit. They describe their company as:
…focused on classic design work from the 1950s-1970s and contemporary designers that draw inspiration from that time period.
Not only do they have great design and type specimens, they also have interesting articles, interviews with designers worth getting to know, and a thread of design jobs.
Ahh…it’s as though they do this just for me. I have literally spent hours sifting through all of the vintagy goodness in this site.
