I also would do Antique
Try an ebay search for Antique Dresden letter holder, This one is under Antiques
Others found on an internet search say antique as well
Nice one that is a two tiered hand painted and decorated letter holder by Limoges France that they say dates back to late 1800's
Your piece is very pretty.
@divwido Nice piece, you might try starting with "antique ceramic tray" ... then once it gets in a better category start the listing and add other words to the title that are appropriate to describe it.
