Cracker was a very special dog. The white bull terrier, with a black spot over one eye and a comical disposition, became the most famous canine model in the world because he was the bosom pal and leading professional model of illustrator Cecil Aldin. In Aldin’s studio, Cracker found his book companion and “straight man” Micky, who was generally to be seen stretched on a sofa. The pair became sleeping partners; hence the title of a series of drawings made over many months and published in book form, with no text except for one-word captions under each picture.
Cecil Charles Windsor Aldin (28 April 1870 - 6 January 1935), was a British artist and illustrator best known for his paintings and sketches of animals, sports, and rural life. Aldin executed village scenes and rural buildings in chalk, pencil and also wash sketching. He was an enthusiastic sportsman and a Master of Fox Hounds, and many of his pictures illustrated hunting. Aldin's early influences included Randolph Caldecott and John Leech.
