I am sure you're sick to death of hearing about the treasures I find at the Book Thing, but this weekend I got a couple of great books that are interesting from a perspective of 20 to 30 years. For a while, I've been writing about whether Carleton Varney's 1970's Book of Decorating Ideas has stood the test of time. For the most part, it has.
I found an interesting book called "Interior Views: Design at Its Best" by Erica Brown, published in 1980 by Viking. This book is a series of two-page profiles of noted interior designers of the day, followed by two pages of colour photographs of a job they've done. It was interesting to see how many names are still current and working, as well as how many have vanished into the mists of time.

I also found the wonderful book, "Mark Hampton On Decorating" with his lovely watercolour paintings and beautifully calligraphied titles. This book has been a favourite for a long time, but I'd sold my old copy when I moved abroad. I am glad I have it again!
I had to show you this hideous picture that shows how dated some designs become. It's by someone called Antony Redmile.
