I haven’t done any film or television prop work, so I was unaware of them, but the Set Decorators Society of America has quite a handy website. First off, they show off the decor in films which their members have worked on. These are extensive photo-essays showing the sets from these films, often without actors in the way. You can also read interviews with their various members.
They publish many of this in their quarterly magazine. Luckily for you, you can download their back issues in PDF form… for free!
They also have a list of resources for shopping, as well as a healthy list of books to check out. Also, the comic above is by my twin brother; click on it and you can check the rest out!
