An early 19th century pressed wood snuff box  of Augustus. Good details.
Lined with red tortoiseshell. On the lid are the words ' Auguste Premier Emperor de Rom'.
These antique snuff boxes were made by turning a piece of wood to a block, then the decorative lids and bases were made by subjecting the wood to steam to soften them and then whilst the wood was slightly soft metal dies were pressed down on to the lids and bases impressing the wood with ornamental pictures. The blocks would then be cut in half to form lids and bases and hollowed out  lined with tortoiseshell
