I found this on Manners Mall. It’s part of a display called Sugarcube, which consists of a wooden cube with sugar sachets stapled to it. Each sugar sachet was drawn on by someone in a Cuba St cafe. The cube is locked in a transparent perspex display, protected from the elements.
I saw this photo, immediately thought of my friend Matt, snapped it, uploaded it to Flickr, then sent the url to Tuatha who confirmed that it was indeed doodled by Matt because Tuatha was there when Matt drew it.
