About Noddy (from Wikipedia):
Noddy is a fictional character created by English children’s author Enid Blyton, originally published between 1949 and 1963. Noddy was illustrated by the Dutch artist Eelco Martinus ten Harmsen van der Beek from 1949 until his death in 1953, after which the work was continued by Peter Wienk. Television shows based on the character have run on British television since 1955 and continue to appear to this day.
Early Noddy books have become collectibles, along with other Blytons. The total number is hard to count: the Noddy Library (Sampson Low) of two dozen titles, which became the New Noddy Library when revised, was just part of a big production in the 1950s, with Big Noddy Books of larger format, and strip books. There were numerous spin-offs, also. Widely differing estimates can be found.
