Yes, Volume I exists!!
I have both copies on my kitchen shelf. The cover has Mickey dressed as a chef mixing something in a bowl with a window behind him that has a view of Cinderella Castle & Spaceship Earth. I bought it when I was still in college, living at home and wasn't cooking yet, but knew I would want it in the future.
This cookbook is old, I must have gotten it literally 15 years ago. I bought my cookbook on Main Street in a shop that sold cooking items. Near where the candy store sits today. They had them for sale for a very long time before and after I got my copy. What I like about it is that it has a listing of all the restaurants that the recipes came from and most of them have since changed names, but it's cool for bringing back memories.
