This famous design by A.D. Copier is the so-called 'Spijkerbol'. This vase or soliflore is made from one piece of handblown glass. It has small air bubbles in it which create a look like it's been poked with a nail, hence it's name 'spijkerbol'. It's in good condition as can be seen in the pictures.
