'The Painted Veil' looks like a re-use of a portrait of W. Somerset Maugham originally published in Punch magazine.
The next one was also published in Radio Times illustrating Steinbeck's 'Of Mice and Men'
Of course Penguin also reprinted the essential collections of Searle's cartoons and St Trinians
Also a fine collection not published in the USA (reprinting some images made for American periodical Holiday magazine)
Searle finalized the 'penguin self-portrait' gag as a Searle-mask wearing bird!
