Q: Hi! Any info on this title? Macbeth

A: Hello, This book is either part of the Classics Series or the Slip in the Pocket Series. Without the dust jacket it is impossible to tell. It was published sometime between 1907 and the early teens.

As can be seen below, the front cover of the jacket names the series.

All of the books of these series are reprints. Since your title is very common and not in great demand, it has little value.
