London, Hamish Hamilton, 1973 (first edition).
Quarto,  pages including a colour-pictorial title page and 28 pages of colour illustrations ('a series of strip pictures, filled with detail and very funny, which occasionally erupt into full-page spreads').
Colour-pictorial papered boards lightly bumped on the two top corners; a near-fine copy with the near-fine dustwrapper (also lightly bumped on the two top corners), unclipped, with a local department store hinged price label attached above the printed price.
From the first sentence ('Blooming Christmas here again!'), this is a classic.
