Taxi Driver #84, Boulder Colo. 1948 Employee Pinback

I really love little things that feel like prompts for imagining whole lives and worlds. This is completely that for me. Boulder had a population of about 15,000 in 1948--clearly with at least 84 taxi drivers to run them to and fro. Who was driver #84? The history of taxis, and taxi drivers, is actually quite a fascinating one to dive into--but i think this is also just an excellent and iconic feeling sort of a button. 

1 1/4" d. General wear and some rusting to the back as documented.
