This was Kenilworth Castle and Kenilworth was an extraordinarily popular book written by the Scottish Author Sir Walter Scott.
The full title is "Kenilworth. A Romance" - though it seems to be a romance that involves a murder. It was first published in Edinburgh in January 1821, quite anonymously, and is one of the so called "Waverley" novels.
You can read it on GoogleBooks/Kenilworth and probably in other places too.
Walter Scott died at his home, Abbotsford, in 1832, after a trip to the Mediterranean on board HMS Barham. It was on his return journey that he suffered one of several strokes and although he made it home he never really recovered. He was only 61.
In our original World Tobacco Issues Index this set is revealed to have come in three versions. The listing reads :
ABBEYS AND CASTLES. Sm. Blue-grey photogravures. Nd. (25)
A. Back in olive-green, wording only.
B. Back in blue-grey, with “Statue of Liberty” illustration.
C. Back in blue-grey, with “Stag” illustration.
Now this needs a bit of explanation, because "wording only" is not a descriptive text, as you may be thinking. Instead it says the number of the card at the top, followed by "Photogravure Series". Below that, beneath a straight dividing line, it says : "ABBEYS AND CASTLES 25 IN THE SERIES" which, after another dividing line says "SMOKE NEW YORK MIXTURE". At the bottom it closes with "EDWARDS, RINGER & BIGG, Branch of the Imperial Tobacco Co. (of Great Britain and Ireland) Ltd."I
As for the “illustration”s, they represent brands, the Statue of Liberty for “New York Mixture” and the Stag for Exmoor Hunt.
None of this is mentioned in our updated World Tobacco Issues Index either, which follows the above cataloguing word for word – except for adding a discovery, that being that in the A version the numbering of the cards is different from the other two.
