Some paintings have to be revisited. For me these include Magrittes In Praise of Dialectics and Peter Powditch's The Big Towel, both in the NGV. Sadly I cannot find a reproduction of the Powditch painting. It is a closely cropped female torso wrapped in a green towel and painted in a pop/Leger kind of way.
Another one is John Brack's Barber Shop (below left). I am not sure why I like it so much but the two men staring out are compelling . However, the one element that makes the painting something other than ordinary is that yellow lamp shade reflected in the mirror above the seated man. To show what I mean I removed it from the image on the right below. The painting loses much more than a little yellow lampshade, don't you think?
