Subseries contains records on pieces of art that Lansdowne produced. Files 35-01 to 35-06 contain an art inventory card index which provides details of works that were sold, as well as those for specific named projects. The contents of each art inventory file vary, but typically include at least one reproduction of the artwork and an envelope which bears a unique alpha-numeric code and the name of the bird(s) featured in each piece. The year of creation is usually written alongside Lansdowne’s signature within the artwork. Formats include photographs (both black & white and colour), negatives (both black & white and colour), positives (both black & white and colour), slides (colour), paper photocopies and textual records. Files 06-30 to 06-32 and 06-34 to 06-36 also include sketches.
