THE YEAR 2007 marks the 65th anniversary of a bold experiment: the launch of the Little Golden Books during the dark days of World War II. At a time when the literacy rate was not nearly as high as it is now - and privation was felt by nearly all - quality books for children would now be available at a price nearly everyone could afford (25 cents), and sold where ordinary people shopped. "Golden Legacy "is a lively history of a company, a line of books, the groundbreaking writers and artists who created them, the clever mavericks who marketed and sold them, and the cultural landscape that surrounded them.
