This book has been out of print for a long time, but can still be found in used bookstores here and there.
There are excellent models included here, but the book’s problem is that the diagrams are not the clearest, and the photographs are quite horrible – they even managed to mess up a photo of Neal’s dragon…
My favorite models in this book are Lang’s Shiva and Neal’s cute wizard and witch.
I wouldn’t recommend this book for beginners, but for advanced folders, who sometimes enjoy a small challenge of “deciphering” diagrams.
