X marks this spot and it never erodes! The first time you spot this 'X' on the wall you’ll notice them popping up over the city. It’s an 'X's that mark the spot but also there’s 'O's too, making a game of O-X-O or tic-tac-toe. At this particular spot I really see the 'X' as having a harmoniously link with the design of the steel balcony. A sympathetic design feature in-keeping with the architecture, in-tune with the concrete landscape as if intended as part of the architects original plan. The artist is De ZeeR's Tic Tac Toe whose designs feature in the Agnes B. boutique near Saint-Eustache.
