Before you hurry to sell your child’s favorite book just because you grew tired of reading it over and over again, check if by any chance it is the 1963 first edition signed copy of Where the Wild Things Are. If so, this next line will sure to wake you up. Such a copy was sold in 2012 for $25,000 on Abebooks.com. Got a mint first-edition copy without Maurice Sendak’s autograph?
Such a version might still rake in some cash! A collector is sure to be interested as the book is well-loved – by its 50th anniversary in 2013, the book had sold 20 million copies.
