I don't know exactly how old this book is, but it's pretty old. My guess (fairly educated...haha!) would be around 1910, based on the binding and cover and font. I love it. It was my first vintage Dickens...I'm a HUGE fan of Dickens.
I'm pretty sure I bought it for $5.00. $10.00 at most. But I think it was $5.00.
Happy Reading! :)
