When’s the last time you saw a car like this on the road or needed an inkwell to write? Antiques can remind us of how much and how quickly styles and technology change.

Every antique tells a story. It’s often one of change, sometimes over a relatively small amount of time. Look at the simple act of writing. Most of us probably have several ballpoint pens scattered throughout a desk — and most of our writing, whether it’s a professional project, a school paper or just filling out a form, is done on the computer anyway.

It’s only about a century ago — not that much time, in the world of antiques — that you had to dip a nib pen into an inkwell to sign your name. Fountain pens, which use ink cartridges, were invented about 1880, but inkwells remained in use into the 20th century. They were often decorative and could be luxury items, made of precious metals, fine porcelain or cut glass. They could also be novelties, like this one, shaped like an early car and made of an inexpensive metal like pewter or spelter, which sold for $82 at an auction by Morford’s Antique Advertising Auctions at antiqueadvertising.com.

It would have been a useful and stylish item when it was made in the 1910s or 1920s, possibly a status symbol for the proud owner of a Model T. Now, it captures a moment in time when writing was done with a dip pen, instead of a cheap ballpoint or a computer screen, and cars were a new advance in technology instead of something in everyone’s driveway.

Q: I bought an old king-size canopy bed, but I don’t know which era it is from. Can you please assist me?

A: Canopy beds were popular from the late 1700s to the early 1800s (often called the Federal period in American furniture), and again in the Colonial Revival of the 1930s. The easiest way to determine the era of an antique bed is to measure it. American bed sizes were standardized by the 1920s. A king-size bed is 76 inches wide by 80 inches long. If that is your bed’s size, it was probably made in the 20th century. Beds made before 1900 are usually shorter and narrower than standard sizes, so it can be difficult to find a mattress that fits an antique bed. Before the mid-1800s, mattresses were held in place with ropes, which had to be tightened periodically. A bed from this period will have holes, sometimes pegs, in the side rails for the ropes. Wooden slats to support the mattress were introduced by the mid-1800s.

Q: I have a cup and saucer a good friend gave me years ago. The name on them is “Royal Carlton” and the number on them looks like “7865” (it’s hard to see). In between the name and number is printed what looks like a cross of two feathers. Both the cup and saucer are covered with pinkish roses. They are both backgrounds of light blue. The cup has a gold circle handle. Most cup and saucer sets are flat in the middle, but this one is raised in the center. I am wondering about the worth of them.

A: “7865” is the pattern number for this design. “Royal Carlton” is a trademark registered in 1957 by Arnart Imports, Inc., a company based in New York that imported custom-made porcelain dishes and giftware. Their products were usually marked “Arnart” with a sticker or paper label. These labels often wore off, so sometimes the only mark on an Arnart piece is the printed trademark. They used several trademarks, including Royal Carlton, Royal Chintz and Royal Crown, and various printed marks. Their printed marks often resembled the well-known marks of famous European ceramics firms. The crossed-feather mark, like the one on your cup and saucer set, is also known as “crossed arrows.” It is a copy of the mark used by the Porzellanmanufaktur Kalk in Thuringia in Germany. Arnart imitated several famous European porcelain factories; they also used a beehive mark like the one found on Viennese porcelain and made porcelain figures that resembled Hummels. A single Royal Carlton cup and saucer will sell together for about $25.

TIP: Clean a glass inkwell carefully. The old ink may cover a crack. Wash in warm water with mild dishwashing liquid or soap, never dishwasher detergent. Don’t use ammonia if the glass is decorated or iridescent.
