Painted Porcelain Plaques

Back in the 1970s and ‘80s, 19th-century small or miniature painted porcelain portrait plaques were hot collectibles. When they came to market they always looked properly old. They appeared to be painted on porcelain as well as ivory. Sometimes the backs were even covered with what seemed to be 18th or 19th century newsprint. Chances are, your mother or grandmother bought one. Was it worth as much as she paid for it? These days it could be worth thousands of dollars or less than $100. If you have one, check the following facts.

Are they what they appear to be? Choice, authentic pieces are marked KPM (King’s Porcelain Manufactory) and were made in Germany. The earliest such marks were painted on Meissen china (1723-24) with crossed swords. However, the KPM signature might be etched on a blank or an inferior porcelain plaque from Austria or Germany. As for the painting itself, it may be a decal of a painting. The use of decals around the 1830s was the revival of earlier styles. Reproduction of those early decals has never stopped.

When considering a pur-chase or a sale, use a strong magnifying glass or a jewelers’ loupe. A decal will show a small dot matrix. Another trick of fakers was to place transfer print plaques under convex glass. This gives the effect of a hand painted piece. Details such as jewelry or hats are touched up with paint. The result is that they are raised under a magnifying glass.

When the small plaques are supposedly framed on ivory, they may actually be on plastic.

By the early 19th century, factories on the continent and in England turned neoclassical paintings, portraits of beautiful women and famous people into decals and miniature plaques. Lady Hamilton and Napoleon were popular subjects.

Pass on a piece when the back is covered with felt and you can’t see makers’ marks. The seller may not even know what is behind the felt backing.

Most fakes are porcelains signed Wagner. However, when it is a hand-signed and hand-painted plaque by the renowned artist Wagner, it could sell for thousands of dollars. You have the clues so do your research if you plan to buy or sell.
