Grossmith, George & Weedon: The Diary of a Nobody (illustrated), v1, 14 Aug 2007
 

I've added a TOC and restored most of the original illustrations.

From Wikipedia:

Diary of a Nobody, an English comic novel written by George Grossmith and illustrated by his brother Weedon, first appeared in the magazine Punch in 1888 – 89, and was printed in book form in 1892. It is considered a classic work of humour.

The diary is that of Mr Charles Pooter, a lower middle-class man, a city clerk, with modest social pretensions. Other characters include his wife Carrie (Caroline), his son Lupin, his friends Mr Cummings and Mr Gowing, and Lupin's unsuitable fiancée, Daisy Mutlar. The humour derives from Pooter's unconscious gaffes and self-importance, as well as the snubs he receives from those he considers socially inferior (i.e. tradesmen). The book has spawned the word "Pooterism" to describe a tendency to take oneself excessively seriously

I remember reading a part of this many years ago in a collection of material from historical Punches. Great stuff. Great find.

Mr. Charles Pooter sounds like Mr. Dursley from the Harry Potter books.

I am beginning to believe that I am the only person in the western world who has never ever read any J K Rowling.

There are two of us, then. I have all seven, er, six books on my reader now, but I have yet to read any. Doctor Who novelisations take precedence.
