Here's a printing history for the Signet editions.

 * - D1858, $0.50, Sep-1961 - not verified but Jim Gardner has an image
 * Some Amazon listings say "1967" but don't give more data. This might be a seller typo as on AbeBooks there's only one seller for 1967 and they say "Signet S1464, 1967 ... First Signet printing December 1967" meaning they gave the date for the Dec-1957 1st but called it 1967.
