Portrait miniatures: carrying a face before photography
A miniature is a portrait made to be carried. Before photography there was no other way: the face was painted on a plate the size of a palm or smaller, set into a locket and taken on the road. Hence the materials – thin ivory, enamel on metal, glass and a mount with a loop.

The supports
- Ivory – a thin translucent sheet that makes skin look lit from within. 23 miniatures here.
- Enamel on metal – the colours were fired, so they hold for centuries without fading. 26 works.
- Lockets and mounts – the miniature as jewellery, with a loop or a pin. The largest group: 60 objects.
- Silhouettes – a single-tone profile, cut or painted; the fastest and cheapest kind of portrait.
How to look at one
- Support. Ivory is translucent and often has fine edge cracks; enamel is smooth, glossy and densely coloured.
- Brushwork. On ivory the artist worked in short strokes and dots – under magnification a mesh of marks appears.
- Mount. An original mount with its loop and intact glass is worth more than a later frame.
- Reverse. A lock of hair, a monogram or an inscription is part of the object's history and stays.
- Signature. Makers signed with initials near the edge; a name changes the valuation sharply.
What lowers the value
Cracked or warped ivory, faded watercolour, replaced glass, a later mount and signs of alteration. Age by itself adds almost nothing: a miniature is judged by condition and by the maker's name.
