This 1909, copyright 1898, edition from Brentano’s contains the fourth edition text, english prose of the ‘Quatrains of Omar Khayyam’ by Justin Huntly McCarthy, and an address by John Hay. The pages are very thin/faded (you can see the reverse side text very easily).
Update 2022-12-07: posted about the cover repair.
Update 03/2026: Updated year from 1898 to 1909 based on Roman Numerals conversion. It doesn’t make sense to me to have a future year if it wasn’t the more accurate year from the copyright year so I’ve updated it.
