Here's an artist I wanted to add before but it's sooo hard to find pictures of his older work and my scanner is crap.
Jan Pienkowski: "He co-founded the greetings card company, Gallery Five. He worked in advertising, publishing, and doing graphics for the BBC children's TV series Watch! In his spare time, he started to illustrate books for children. The books took over. He won the Library Association Kate Greenaway Medal in 1972 for his silhouette illustrations to Joan Aiken's The Kingdom Under The Sea and again in 1980 for Haunted House. He was to use his silhouette technique to dramatic effect in other books like the Fairytale Library.
Jan pioneered the modern Pop-up book with Haunted House (subsequently on CD-Rom), Robot, Dinner Time, Good Night and 17 others. Christmas Kingdom, Phone Book and Door Bell added sound effects while Botticelli's Bed and Breakfast capers irreverently through the history of western art." www.janpienkowski.com
Love love love his silhouette and color illustrations for Joan Aiken.
