He was quoted as saying, "I have never been able to understand why cheap books should not also be well designed, for good design is no more expensive than bad." Edward Young designed the horizontal bands and used Gill Sans Bold for the title's letting. He was also sent to the Zoo in Regents Park to sketch penguins for the cover. Allen Lane wanted a cover design that was consistent and easily recognizable. In 1937 the font was changed to Times New Roman. His Pelican Books were non-fiction books. Penguins were meant to entertain while Pelicans were meant to enlighten. In the 1950s his company had grown so much that it had major outposts in both Australia and the United States. Lane's management style put him and the individuals in charge in his United States office at odds. These individuals eventually left Penguin books and started their own publishing companies: Bantam Books and New American Library. The paperback venture was extremely successful, and he expanded into other areas such as Pelican Books in 1937, Puffin Books in 1940 and the Penguin Classics series in 1945. Lane was responsible for the decision to publish an unexpurgated edition of D. H. Lawrence's "Lady Chatterley's Lover" as a means of testing the Obscene Publications Act 1959. In 1965, during an attempt by chief editor Tony Godwin and the board of directors to remove him, Lane stole and burnt the entire print run of the French cartoonist Siné's book "Massacre", which was reportedly deeply offensive. Lane dismissed Godwin, and retained control of Penguin, but was forced to retire shortly afterwards after being diagnosed with bowel cancer. He died in 1970 at Northwood, Middlesex.
