I remember seeing those SIGNET Bond books for sale back in the 1960s. About this time the ISRAEL BOND spoofs came out.
Playboy did a Annie Fannie cartoon about James Bond vs Israel Bond.
I also remember when Columnist Bob Green had a fit in print about the MOONRAKER novel he bought, not being the Ian Flemming book, but a novelization of the movie.
The best James Bond movie is still FROM RUSSIA WITH LOVE.
