I loved
The Three Musketeers and my first introduction to it was The Windermere series of
The Three Musketeers published by Rand McNally & Company, 1923, Hardcover, Milo Winter (illustrator), Translated and arranged by Philip Schuyler Allen, The University of Chicago - The seven color illustrations are beautiful.
This edition was specifically for children, even though it is still over 500 pages of text and the preface does state that the translator did remove parts that were "slightly soiling or unclean, and which seemed to dim the pure brightness of the rest of the book."
It was pure adventure and my brothers and I would check it out from the library often (along with the Marco Polo one). We finally were able to own it, when the library sold off very, old books and we were able to get one that still has a check out card from 1948. I still have the book, although I haven't reread it in many years. I have read other versions of which is one by HarryT in our library here -
Dumas, Alexandre: D'Artagnan Romances, Vol 1. v2, 22 Aug 2008
The Man in the Iron Mask (the last of the story) was also a favorite one of mine and I have that in a stand alone hardback book. It is also available here in our library, again by HarryT,
Dumas, Alexandre: D'Artagnan Romances, Vol 4. v2, 22 Aug 2008. To me, the books were always much, much better than any of the movie versions.
