If you are at all interested in Vintage Patterns, you need to check out Blueprints of Fashion by Wade Laboissonniere. He's got a book on the 50s and a book on the 40s, and each one is a treasure trove of patterns. The books contain information on the industry, marketing, and of course lots and lots of lovely pictures of vintage patterns. While I do buy vintage patterns, I don't really consider myself as a collector. This book is great for folks like me who just like to get ideas for things to make, as well as people who are a little more serious in their hobby. (As per usual, you can click on the photos to get more detail.)
I bought the 50's book.

The 40's book (Checked out from the library, but soon to be bought.)
The pattern on the lower right is one of my all-time favorites.
