The book contains all the classic lines - "By the hair of my chinny chin chin, I will not let you come in" and "I'll huff and I'll puff and I'll blow yourself in". The story does get a little more complicated than I remember it though when it comes to the third pig with the house of bricks. Although the first two pigs get eaten up (no sanitised version here), the third pig spends the last two thirds of the book outwitting the wolf before the wolf meets his inevitable fate in the cooking pot.
The illustrations in the book are a little more cartoonish than you usually see in a Ladybird book, perhaps because it is animals rather than humans that are being portrayed. Although at an easier reading level I think it would still be a challenging book for a new reader, but it would also be great for reading aloud to younger children.
