Q: Hi there, Another copy I couldn’t identify (Rubaiyat of Omar Khayyam). Pls help.
A: Your book is part of the Petit Trianon Series. As with all of the books in this series, it is a reprint.
It was published in 1905-1906 and originally came within a labeled box. I am including a picture of what the box looks like.
