Quite Old

For about the cost of a jar of Nescafe, I've acquired 3 volumes of David Hume's 5-volume The History of England dated 1796, albeit in 4 parts. 

Clockwise from top left: 
  ~ Volume 1 minus its front cover,
  ~  Volume 3 minus its front cover,
  ~  the detached front cover of Volume 3,
   ~ Volume 5 intact.
