Guardroom scenes often included mercenaries and prostitutes dividing booty, harassing captives or indulging in other forms of reprehensible activities.
[7] Tilborch painted a Guardroom Interior with Armour and a Standard Behind (sold at Sotheby's on 10 July 2004 in London, lot 172), which depicts two soldiers and a woman drinking and smoking in a room.
In its general arrangement and specific details such as the figures and the armour on the floor the painting is based on the signed composition of Tijssens' master Anton Goubau in the National Gallery in Prague.
It is likely that Tijssens' painting was cut down as on the extreme left margin the nose, moustache and chin of the figure next to the woman are visible.
[9] It is possible that in line with the moralizing intent of the genre, the armour is a reference to the vanitas motif of the transience of power and fame.
