They stopped putting pictures of smiling babies on tins of Baby Food for the very reason John suggested. In Third World Countries, many people are illiterate, and even fewer can read English, so when the multi-nationals moved into the market, they were shocked to discover that people refused to buy it, as they too were working on the idea that the picture on the outside of the can suggested the contents.

A few years ago, and artist had a display of interesting objects at the Brisbane Art Gallery, and one of the objects was a very old tin of baby food with the big picture of the baby on the outside of the Heinz Baby Food can. Associated with all teh other objects, it was just as funny as they were.

Of course a picture of mush is not very interesting really, and we are back to John's original problem - how do you tell the different types of mush apart?
