This white metal and mother-of-pearl oval snuff box above opens to reveal a half-length miniature portrait of a lady with an articulated arm holding a fan, which moves with a tiny leaver to cover then reveal her face.
The sitter is possibly Marie de Medici, the second wife of King Henry IV of France, who was noted for her ceaseless political intrigues at the French court and extensive artistic patronage.
The Continental late 18th century box comes from a private collection and is offered with an estimate of £300-500 in the Country House Sale at Tennants of Leyburn, North Yorkshire, on April 27.
This American poster above calling students to strike was pinned to a wall at Harvard University in 1968 – a year marked by escalating protests and civil unrest worldwide.

This mountain view above is one of more than 50 market-fresh drawings from the studio archive of the Victorian and Edwardian artist George Hodgson (1847-1921).

Born the son of a Nottingham braid manufacturer in 1847, Hodgson was closely involved with the Nottingham Society of Artists until shortly before his death in 1921. He exhibited at The Royal Academy and is best known for his drawings of coastal scenes and places of interest around the country.
