This is one (nr 12) of 13 little sculptures of Isaac Cordal placed in the city center in 2017 in cooperation with the city of Brussels. Look closely, his sculptures are no bigger than 5cm! This one is right next to nr 13. I advice you to enter the galleries through the enterance in the 'predikherenstraat'. You'll see the sculptures at the end of this side-arm of the gallery.
