I've probably got 25 books, some dating back to the early 70s. About half hardbacks. One of them is a weird one where all the names are different. I think it was translated by a different group. One is in original French and the names (other than Asterix and Obelix) are all different. They were all play on words.
I've also got all the Tintin books, some hardbacks and some not, and some of them date back to the early 70s.
All of them are dog eared. I wore all of them out as a kid.
