One of the first canvases I ever purchased, Stacked Bars from German gallery Artline in Erfurt adorned the walls of my student room at University. I liked how the architectural steel linkages between the canvasses invited the wall to become part of the artwork [that and it was easy to dismantle and transport home at the end of every term!]
While I wouldn't necessarily buy Stacked Bars now, and it does take up valuable 'wall estate' which could be used for work with more pedigree, establishing a narrative over time is as important for a collector as it is for an artist. As far as collections are concerned, it's easy to make new additions, but considerably less easy to make old additions.
