AMC's breakout show Mad Men is like Gossip Girl, but with more smoking, drinking, cursing, racism, misogyny, and extramarital (or intermarital) sex! Plus, there's no voiceover. Show creator and Sopranos vet Matthew Weiner is a notorious fiend for authenticity true to the 1960 period, which mostly manifests in language, attitudes, clothing, and set design. But Mad Men is also about New York, and there are many real New York locales of the era appearing as straight re-creations or in subtle visual tributes. Hat tip to the troops at Metafilter for noticing a few; I'm sure I missed others, so feel free to point 'em out in the comments or via email. Meanwhile, here's a guide to the New York of Mad Men through the first nine episodes.
