Photographer Anthony Kurtz visited Femme Auto in Senegal and took portraits of the mechanics and auto body workers there. They're really gorgeous shots, and it's always great to see badass women doing it to it in a male dominated field.
Through my limited research, I found a few female-run mechanics and auto shops throughout the world, including ones in Texas and Toronto. Very cool.
