This bottling "The Gaper" celebrates the 6th anniversary of Wijn- en Whiskyspecialist van der Boog / Passion for Whisky

A gaper is a stone or wooden head, often depicting a Moor, on the front of a building in the Netherlands. It was used to indicate that the building is a pharmacy. 

The literal translation of "gaper" would be yawner; the figure is always displayed with an open mouth, sometimes with a pill resting on his tongue. This indicates that in fact he wasn't yawning, but opening his mouth to take medicine.
