Illustrated costume design with fabric swatch, bearing the name 'Sally Kathryn Nuttall'

This item is an original costume design illustration on textured watercolor paper. The work features a stylized figure depicting a maid's uniform, rendered in what appears to be watercolor or gouache washes of muted blue-grey and white. The figure is shown wearing a long-sleeved dress, a full-length white apron, and a matching cap. In the upper right corner, a small, dark grey ribbed fabric swatch is attached with a black fastener, which is stylistically consistent with theatrical or film production design plates. Hand-written notations on the piece include 'Hercules the Mute' in cursive at the top left and 'Maids' at bottom left. The bottom right corner bears a signature or hand-printed name reading 'SALLY KATHRYN NUTTALL'. The paper shows slight yellowing consistent with age, and minor surface wear at the edges. While the signature is legible, it remains unverified without physical inspection or professional authentication of the artist's hand; therefore, this is considered a work attributed to Sally Kathryn Nuttall. The style is consistent with mid-to-late 20th-century costume rendering techniques used in stage or screen production design.

I have examined the digital image of the costume design for 'Hercules the Mute' featuring a signature consistent with the hand of Sally Kathryn Nuttall. Based on what I can see, the piece displays professional rendering techniques typical of mid-20th-century theatrical production, including the integration of a fabric swatch and specific notations for character and role. However, I cannot verify the medium or the age of the paper through a photograph alone, nor can I confirm the signature as having been made by the artist's own hand without a physical inspection. The value of $400-$700 assumes the attribution to Sally Kathryn Nuttall is correct. This estimate is based on general market demand for mid-century production art; similar costume renderings attributed to known designers often occupy this price range depending on the fame of the production. The presence of the fabric swatch adds significantly to its appeal for collectors of stage history. To confirm the piece's status, an in-person examination by a specialist in theatrical ephemera and a review of the provenance would be necessary. Should the work be identified as a high-quality reproduction or a later 'in the style of' copy rather than a production-era rendering, the value would likely decrease to a decorative range of $50-$100. Conversely, if the production 'Hercules the Mute' is linked to a major recognized institution or a notable film/stage premiere, the value could exceed the current estimate. Currently, the market for original production art remains stable, with specific interest in pieces that document the tactile design process, such as those with attached swatches.
