Take a look. I'm still working on it but these are the first groups of thought and I'm pretty sure that its a little to tangential. just gimme a shout back so I know for sure. I do think it would be an interesting way to make my icons have a broader meaning.
the darker outlined bubble around the fifties group is to help with legibility and distinction.
If I were to tell you now, I'd say I'll use the icons in a symbolic way. Maybe the gumball for capitalism; the booth could represent the people of the hour (fifties), and could start a tangent that covers cultural info; waitress- capitalism or some sort of reference to class and wage workers.
