Writing about presents, I remembered another present which I received at Christmas (or New Year's Eve) as a child (I think I was 9 or 10 years old), which exploded my imagination and fascinated me for many years: 50 books with all novels of Jules Verne in a Greek translation by Edition Astir. At that time I had read 2 books of Verne (Journey to the Centre of the Earth and Tribulations of a Chinaman in China). I still remember my surprise after opening the package and seeing all these books in their coloured covers.
In the next years I read almost all of them. It was a journey to a world of unlimited imagination and solid constructed stories full of invention power and fine humour. An amazing present!
