I can't find much information on Curtin Promotions, Inc, but it seems like they sold a lot of "Do-It-Yourself" books in the 1970s.
This The Complete Family Interior Decorating Book has a ton of fantastic information on everything from How to Build a Color Scheme (1970s Style) to a tutorial on "Period Pieces" to a Wallpaper Estimation Chart.
Bound in a 3-ring binder, you can remove certain supplements or add your own notes. This is 480 pages of 70s awesomeness
You are really buying this for all the 1970s interior décor pictures. They. Are. AMAZING.
