Costume design illustration attributed to Sally Kathryn Nuttall

A mixed-media costume design sketch on white textured paper, featuring a stylized character illustration and fabric swatches. The drawing depicts a figure in a hooded, reddish-brown tunic or surcoat with vertical 'x' stitching details, layered over a yellow long-sleeved garment with puffed sleeves. The figure has a grey beard and no distinct facial features. In the верхний left corner, the handwritten text 'PROSPERO' in gold or bronze paint is visible, with the word 'FIRE' written below it in a smaller, lighter script. Two small rectangular fabric swatches in shades of brown and beige are taped to the upper right corner. The bottom right corner bears a cursive signature reading 'Sally Kathryn Nuttall'. The artwork appears to be a theatrical design, possibly for Shakespeare's 'The Tempest', given the character name. The paper shows slight natural warping and is placed on a textured grey background. As the piece has not been physically inspected for provenance or paper age, the attribution to the named artist remains a hypothesis based on the visible signature. The condition appears well-preserved with no significant tearing or staining visible in the image.

Based on my examination of the provided image, I have evaluated this mixed-media theatrical costume design. The illustration features a stylized depiction of Prospero, bearing a signature consistent with Sally Kathryn Nuttall. I can observe typical design elements such as fabric swatches and character-specific annotations, which suggest a professional production context. From the photo, I can determine that the mixed-media application appears consistent with mid-to-late 20th-century illustration techniques, though I cannot verify paper age, pigment composition, or the specific production history without a physical inspection. These values were calculated under the hypothesis that the attribution to Nuttall is correct. The market for mid-century theatrical design is niche, with demand driven primarily by researchers and costume historians. The estimated range of $400 - $800 reflects what similar signed costume sketches generally achieve at specialist auctions when linked to recognizable theatrical productions. However, it is important to note that without verified provenance or an expert authentication of the signature, the piece might be considered a student work, a study 'in the style of,' or a later reproduction, which could reduce the market value to $50 - $150. A physical examination is necessary to confirm the materials and the age of the adhesive used for the swatches. To confirm the identity of the artist, I would recommend securing a provenance trail, such as records from the theatrical company involved, or a comparative study of the handwriting against documented archival examples of Nuttall’s scripts.
