Sadly I don't own this book - a friend of mine picked it up in a bookshop in Edinburgh and I was able to took a photo of it. The pen and ink illustrations inside are even more impressive. Ardizzone(1900-1979) is one of the greatest British illustrators of the 20th century and I'd love to own one of his original illustrations (even though I don't imagine they're cheap!). Here is great website dedicated to his life and work where you can view some more of his work: http://www.edwardardizzone.org.uk/
Some more pictures by Anna Zinkeisen I found from the Internet. Her paintings are very interesting and quite different from the illustration work. The one below is a self-portrait. Very competent with the brushwork and colours as well as excellent composition. The subject matter seems to have been limited to society portraits and mythical scenes though.
These are taken from the 1939 Picture Show Annual. They are signed by K Gol (if I am reading it correctly). Never came across this artist before - his lines are so expressive and skillful especially on the faces.
Not sure of the exact publication date of this one - I can only assume it was sometime in the thirties. I haven't a clue about the subject matter either as my German is non-existent! There are pirates, doctors, wolves together with a harlequin and Napoleon for good measure - I'd love to know what the story is about. The illustrations are so expresive and witty while being drawn in such simple lines. There are eight coloured plates in the book and sixty black & white ones, all full of funny characters in strange situations!
