I will be posting more info on window displays, and as an aside, there are many books available today on window design. Here's a peek into one of the only bookshelves I have organized by subject:
If you want the creme-de-la-creme of this bookshelf, definately go for the "Windows at Tiffany's" book. If you can be patient while looking, you can sometimes get it for a good price. This is a coffee table book and is NOT rare, so just set a budget of at least $75 and be patient - you will get it for your desired price. This book can go for $250 or more.
Oh, and as an aside, my antique books on window dressing and design that are 1920 and earlier are either stacked on top of or in front of these books, as I double stack my shelves.
More coming soon!
