Priced by looking at what has sold on eBay, Abe Books and Goldstone Rare books.
Lots of copies of this around BUT some at a ridiculous price! Priced against two private copies on eBay of the same copy, based GOOD, this is FAIR.
All books listed were owned by a respectably old collector who over 102 years of life invested significant time in the literary world.
Nearly every book (unless otherwise stated) will have an owner's mark such as name, gift, date etc usually in writing.
