vintage patterns

I have found some of the most wonderful vintage dress patterns on Ebay.

This pattern I bought for just over $5! I am really happy and I'm planning to make the sleevless straight dress in a blue/black/white check for work. Some other patterns that I was bidding on ended up going for a lot higher than I was willing to pay for them. I suppose you could look at these patterns one of two ways:
A) A great historical piece to be kept in pristine condition; or
B) A great historical style to be made and worn again and again!
I am going with the latter view.
