Now go outside and look at the sky.
Must Credit ACME
James Lileks' site is one of the biggest time-sucks that I ever encountered on the Web. I can spend hours doodling around in the copious archives full of the old, outdated and wonderful (for a good time, check his collection of vintage Motel post cards!).
Here's a section of his site called Must Credit ACME where he uncovers long-forgotten newspaper photos from the ACME agency in New York. James has access to these old photos through his job at a newspaper and he dives deep into each of these detailed shots of the life of New Yorkers in the 1940s and 50s.
The photos have an intense aura of lost innocence and are dripping with nostalgic street signage, vintage cars and people wearing suits and dresses. Good Stuff.
