I voted for the Hobbit, even though it was first read to me by my father.
The first translation of the Hobbit in Finland went by a name "The Dragon mountain". It was considerably abridged and formed into a children's book: all the dwarves' had funny bedtimestory names and so on... The illustrations were nice though. They had been made by Tove Jansson, the author of the Moomin -characters with which some of you might be familiar with.
But still. Luckily we got a whole translation with more loyally tolkienish names & stuff at the 80's. Kind of missed the illustrations though.
