Not just an "old style Ink holder," this inkwell and lid mechanism was specifically used by draftsmen when inking technical plans drawn on linen. The draftsman would open the lid to refill his inking pen, but, otherwise, the inkwell had a tight seal on it to prevent spillage, thereby spoiling the entire drawing. The same draftsman would use a sander—a perforated-top shaker similar to a salt or pepper holder—to aid in drying the ink. He would then brush off the entire drawing with a traditional thin draftsman’s brush.
