My favorite picture in the book is an amorphous blob with the word `potato' written next to it. Maybe I'm missing something, but if you need the words to explain what the picture is, what's the picture for exactly? Also, good idea making it too big to fit even in a coat pocket and too heavy to take anywhere.
The `Point it' book by contrast is very small and has lots of photos. You could easily use it to order a Bombay martini anywhere in the world, which is the standard that should be used to evaluate a picture dictionary.
