This was phenomenal. It helps to be a guinea pig lover to appreciate some of the humor and artwork, but you don't have to be. For an ABC book, there's a lot going on.
The pictures are detailed. Give a good, long look to see if you can spot everything. Some are more detailed than others. My favorite was Wobbly for W, as even the letter is used in illustrating the word.
I wish I had this book as a kid. Somehow, I missed it, even though I was about 14 when this was first published. I can't have guinea pigs anymore because of my dogs, but at least I can enjoy guinea pig books like this.
I read this on the Open Library, which used a digital scan of the original hardback book. It even included the back cover.
