Harold and the Purple Crayon Series
The Harold and the Purple Crayon series was originally created in 1955 by Crockett Johnson who both writes and illustrates these books. They are fun-filled adventures for the preschool through kindergarten age group: Harold, always in control with his purple crayon, both creates his own adventure and draws himself out of a variety of scrapes. They are full of imagination, creativity and gentle humor. They do not need to be read in any particular order.
Be aware that there are a number of books written more recently by various authors wishing to continue Harold's adventures with his purple crayon. These books differ significantly from the original Harold and the Purple Crayon books which are all written and illustrated by Crockett Johnson.
