WOW ... Sums up this book. With pages upon pages of fantastic full color pictures, lots in actual toy size this is a must have, two thumbs up, stop everything your doing right NOW and run to you computer and get it. Clear descriptions noting variations in boxes and just about everything else you won't be disappointed. The story of Mattel, Ideal and Colorforms companies makes for easy reading and is interesting, even for the "non" collector. I loved all the NASA and real life tie-in information too. Three words sum this book up "GET ONE NOW" WOW
