Step back 15,000 years as a modern boy enters a Stone Age village and learns a few prehistoric tricks of the trade. One day a boy falls down a hole, and an amazing thing happens — when he wakes, he’s in a camp full of people wearing animal skins! Mixing flight of fancy with prehistoric facts, Satoshi Kitamura ushers us back to a time of surprising innovation and artistic expression, shown in cave paintings visible to this day.
