Two Laughing Boys with a Mug of Beer

Two Laughing Boys with a Mug of Beer is a painting by Frans Hals showing a Kannekijker. Someone looking into a mug refers to an old Dutch word for a glutton, greedy for more. This visual theme was also used to depict sight as one of the five senses, and various people have argued about whether this portrait was meant as one in a series of the five senses along with Two Boys singing for hearing and a variant version of The Smoker for smell:

The theme of looking into a mug was also used by Hals when he painted the portrait of Peeckelhaeringh who turns to the viewer to show his mug. This painting of two laughing boys with mug of beer is in the collection of the Hofje van Mevrouw van Aerden and was stolen on 27 April 2011, but was recovered on 28 October 2011.
