Coll.: unknown

This painting has a particularly complicated history. It was first exhibited at the NGV in Feb.1983, as Amphetamine (Spot the Difference), and then at Roslyn Oxley9, 6/83 as Spot the Difference (B) – in each case together with Spot the Difference (Fast) 1983, its green ‘twin’. As shown in 1983, it took the form reproduced here (via slides in Arkley’s archive and the Monash Visual Arts slide library).

Sometime between 1983 and 1994, Arkley evidently modified the canvas, adding extra shading; revised state also shown here – compare e.g. the feet and mask at upper right. The changes are in tune with the spirit of the puzzles from which these works take their name (for comments, see Spray 60 and Carnival 79).

The canvas was reproduced in its revised form in the Sotheby’s 1994 auction catalogue, then in Spray, and more recently in a Melbourne real estate advertisement (for details, see references below). In either its original or modified form, the work may also have been shown in HA Quentin 2/85 as Spot the Difference – Slow, although the lack of installation photos leaves it uncertain whether it was actually shown there at all.

The painting was auctioned again shortly after the artist’s death, in November 1999, and again in October 2000.
