A First Edition of Proust recently hit the auction block. Yikes! This is not chump change.
Lucky buyer lucky seller World Record for Proust First Edition if Swann's Way
I have an ancient edition of two volums of the entire novel that I bought in Houston when I attended Rice. In those days of yore, I patronized a bookstore that had many books from the Seamen's Library in Galveston. Some of them were waterlogged, so they might have gone though the great hurricane. My copy of Proust (in English) is a bit ratty but holding its own. Been read a lot.
How is YOUR copy of Proust? Is it a First Edition? You are in luck.
