Goblet holder

A goblet holder, or Bekerschroef, is a specific type of wine glass extender used for ceremonial occasions in the Netherlands during the 16th and 17th centuries.

[1] Many Dutch group portraits of guilds feature members holding one with a wine glass or rummer, in it.

They were also often featured in still-life paintings, possibly to commemorate the banquet or feast of the holder.
