A miniature 17th century portrait of Henrietta Maria, youngest daughter of French king Henri IV and Maria de' Medici, by British artist John Hoskins, is to auction next month.
The work will arrive at Bonhams London on November 21 with an estimate of £20,000-30,000 ($32,369-48,554).
Henrietta Maria married English king Charles I on June 13, 1625 and moved to England where she lived as Queen Consort until Charles was executed in 1649.
Jennifer Tonkins, head of Bonhams' portrait miniatures department, commented: "The muted colour palette and dignified countenance of Queen Henrietta Maria are exemplary of Hoskins' work during the reign of Charles I.
"The artist began his career painting in oil but excelled himself as a limner, securing permanent employment at the royal court by 1640."
Earlier this year a miniature by Peter Stroely sold for £18,750 ($28,505) at Bonhams London.
