I loved this when I was a kid. I had a copy when I was a kid. I couldn't hold out and finally bought a replacement copy in 2022. I have the 1977 Puffin paperback edition, but it wasn't any different from the earlier editions.
This is the first book in the Flip series. You do not have to read this book in order to understand the next books in the series. They are all self-contained stories.
Wesley Dennis was one of the most unique of equine artists. His horses still were realistic (more realistic than his people) but often had a slight human or comical quirk to them. A Wesley Dennis horse drawing is like looking at an expertly cut diamond. There is one small flaw purposefully put in to make it look more real than real.
You can appreciate the art, no matter what your age. The story is about overcoming small obstacles. Some might sniff that Flip the Foal has a dream, but it has been proven that horses dream.
Enjoy.
