How much is a bozo the clown record and story book combined worth copyright 1947?

It would really depend. Bozo the Clown was the name of a popular children's TV show character, and various cities had their own version of him-- in other words, a different television actor played him in different cities. But the cartoon story-book version of Bozo might have some value, depending on what condition the book and record are in, and whether it is considered a rare item. (The year it was copyrighted is not necessarily the year the record company issued it to the public.) I notice on eBay that some Bozo books/record combinations are selling for $17, while others are selling for as little as $1. You may want to go onto eBay and see what similar items to yours are getting.
