A watercolour showing a detailed view of a "temple" mantel clock, after RCIN 30261. The white marble clock case is shown crowned by a stylised finial and resting on a classical-style canopy, supported by four columns. A vase finial is shown above each column. A draped female figure is shown standing under the canopy. She is shown playing the flute with a gilt scroll at her feet. The whole is shown resting on a tiered marble base. A plan for a glass cover us shown to the right, with a further loose plan to the upper left. A single pen and ink line border is shown around the edge of the sheet.

The Pictorial Inventory consists of three volumes containing a total of 230 drawings. It was originally created as a pictorial record of the clocks, vases, candelabra and other miscellaneous items from Carlton House, as well as selected items from the stores at Buckingham House, Brighton Pavilion, Hampton Court and Kensington Palace to be considered for use in the refurbishment of Windsor Castle. Artists from an architectural drawing school run by Augustus Charles Pugin were employed by George IV’s supplier of furniture, Nicholas Morel, for this epic task. After Morel had finished using the drawings as an aid in creating his furniture schemes for Windsor Castle, the drawings were bound into three volumes and delivered to the King’s Inventory Clark, Benjamin Jutsham, where they assumed the role of an inventory. At some point in the nineteenth century, further drawings were added to the original 214 supplied by Morel. Many of the 230 drawings have been annotated by Jutsham or by a later hand and many inscriptions, including some signatures, have been erased.
