What was an image used by martin luther king jr. in his "i have a dream" speech?

I'm not exactly sure what you mean by this, but towards the end of his speech he said something to the effect of wanting to see "all the little black boys and all the little black girls" holding hands with "all the little white boys and white girls." This part of the speech gave listeners gave something to imagine of what he wanted for the future. It placed an image into people's mind, so I guess this could be an answer to your question if it's asking what I think it's asking.
