COLOURING BOOKS FOR ADULTS

Ladies and gentlemen, note that I wrote colouring books for adults lest some norty ones might perceive them to contain pornography.  There was an article in the newspaper about this being a hobby for some adults who find it relaxing and to de-stress in a wired world.  Helps to ones inner being.
For your information, I bought one and will try colouring to de-stress.
