Wax Works

Today at school, Gemma's class had a wax museum. Each student dresses up as someone famous, and when you push the coloured button, they recite a few lines and you have to guess who they are. Gemma took this very seriously and while there was sometime chaos around her, she stayed in character (making it hard to get good photos!)

Gemma was a bus riding lady who stood up for her rights. Any guesses who she was?
