The Rubaiyat of Omar Khayyam:
~1890s Henry Altemus Edition

A chunk of pages are missing from my copy of this Henry Altemus Rubaiyat of Omar Khayyam edition. Unfortunately, those pages probably contained more approximate information on the year of this edition. Based on web searching, similar Altemus copies of other books come from the 1890s.

This website was helpful in learning more about the Henry Altemus Company and this edition.
