The artwork in this collection was created by Allen Biller during her earlier years in England as well as during her time in Canada. Her earlier works, particularly those completed before immigrating to Canada, were often illustrative commercial works, intended for publication in books or periodicals, as well as for other commercial purposes such as Christmas cards and book plates. Her later works include more landscapes. The Artwork series is divided into 5 files: Original drawings, Published works, Significant unpublished works, Landscapes, and Other artwork.
