PageBoy book holder
The PageBoy book holder is one of the handiest gadgets that I own. It could not be simpler in design, but I have found it works well to hold all sizes of books, from I use mine for holding workshop and cookbooks to paperbacks. The other book holders I have seen on sale in the UK have been cumbersome and expensive affairs. The PageBoy is really cheap.
I discovered the PageBoy in a bookstore in Santa Barbara many years ago. Since then I have bought several more. I have three around the house and have given several as gifts. The company only has a very basic website and I used to order directly from Ted Million, owner of the company that makes them. Since then I have found some websites that sell them.
