The Later Works of Aubrey Beardsley from 1920.
This is a hard-cover an with uncommon dust-wrapper. There are blue cloth boards with slight wear to the edges and a brown dust-wrapper with some chips to the edges but quite intact.
 The book has rough cut pages with slight browning, more so on the preliminaries. There are numerous, clean black & white illustrations. The book was published by John Lane:the Bodley Head. 
A very good copy.
