I'm helping a middle schooler who was assigned Shaw's Pygmalion. I found a nice write-up about flower girls but now I need something about dustmen. For example, why does Alfred Doolittle, dustman, wear leather? I'm not looking for that question to be answered here -- this is just an example of the sort of information that should be included in the write-up I seek.
This is the closest I've gotten so far, but that text is confusing.
The other study guides I've tried have character analysis of Doolittle. I'm looking for straight historical information about the trade of dustman.
