Citing Works of Art or Objects in Chicago Style
Citing a work of art by a known artist, according to the Chicago Manual of Style:
Artist First-name Last-name, Artwork Title, date, material, dimensions, owner of work (such as museum), location, URL (if you found it online).
Here is an example from the Metropolitan Museum of Art:
Jean-Auguste-Dominique Ingres, Comtesse d'Haussonville, 1845, oil on canvas, 51 7/8 × 36 1/4 in. (131.8 × 92.1 cm), The Frick Collection, New York, https://collections.frick.org/objects/105.
Museum objects without known creators, most of which are in the public domain, are cited differently.
See this Q&A from the Chicago Manual of Style for a complete discussion of this subject.
