The bottom of the document cabinets for "Footstep" measures 104.3 cm x 54.5cm, with a 1cm diagonal "cut-off" at each of the 4 corners. The height of each cabinet is 26cm. Perhaps the painting collages should be made to fit the cabinets ahead of the set-up day on Nov 8?
If the painting can be fixed up before Nov 8, then will be avioded some unexpected incident on set up day ! But the compostion will be a main concern between the paintings and slabs !!
