I came across this whilst wandering through the back issues of The Age..

I remembered discussing it with friends over morning coffee earlier in the week, when we were discussing Australian cartoons vis-a-vis American ones---it was generally felt that Australian cartoons have more bite than American ones. The latter are dummed down so as not to upset the advertisers was the argument.
That used to be the case in Australia aroung the time of the cancer cigarette links were going public.
This cartoon was mentioned as an example of the reader sometimes not being able to figure out what is going on.
I find it one of those dunno ones.
