An oil portrait from the 1850s has sparked a quest to identify its creator. The painting depicts William Denton, a butler employed at Wentworth Woodhouse near Rotherham, but the artist remains unknown despite leaving only a cryptic mark on a wine cork within the composition. The work had languished in an attic for decades before Denton's descendants brought it to light, had it cleaned, and had it framed for display.

Now featured in a new exhibition at the historic house, the portrait raises intriguing questions about its origins and commissioning. Given that artistic portraits were typically reserved for the wealthy, Denton's relatives puzzle over whether he paid for the work himself or whether a visiting or amateur artist painted him at no cost. The image has become part of a broader curatorial effort to tell the stories of household and working-class residents, deliberately expanding the house's historical narrative beyond its aristocratic owners.
