I know it was long overdue but I just started watching mad men and I am adoring everything. It was impressive the way they captured the atmosphere, the styling, the interior designing of the 60's. I like the plot too
(and the cast more).
I looked into to it and it turns out the set decorator Claudette Didul has wan several prizes for her work in the show and here is an interview with her talking about the sets.
I found the photos above here as well as a lot of other cool sets.
Probably there will be more talking about the show soon.
