Signs and signifiers

Today we were looking at the meanings of illustrations and signs, whether they are iconic (cat mug) a symbol (swimming badge?) or another option that I can’t remember! I get a bit tied up with these ideas, I will get it, I know, but just trying to explain it makes my head hurt.

Anyway it’s surprising how much illustration there is around us. My favourite is the Ludford Ginger bottle. What had the train got to do with it?
