Norman Rockwell Clock made by Ridgeway.?

I bought a Norman Rockwell Clock that looks like a book but when it opens its a clock. It says on the front it is an anniversary issue The Saturday Evening Post june 94'. The Norman Rockwell museum-Cure for Ulcers Stomach Exercises-seafood & pasta recipes. It is made by Ridgeway Serial number 95029799. It is very nice clock. Does anyone know anything about it: when It was made and how much is it worth? I can't find anything like it on the web. So i turn to you all for Help. Thanks
