Not perfect shape, but no writing, no tears, no marks of any kind. It's honestly in great shape. There was a distinct mildew odor to it (though no visible mildew) which I remedied with the painstaking application of alcohol to each and every page, etc.
This isn't a true first as it has the red end papers. Still very nice find.
Looks like a 2nd printing, I think? It should still have the red endpapers, though, if it's a 2nd. What's it say on the title/copyright page?
You sir, are never wrong. 2nd edition.
@Anthony : "never" is only a wee bit of an over-statement ;)
