The American Vecturist Association is a group that loves to collect and study things called transportation tokens. These tokens are like special coins or small objects that people used to use to pay for rides on buses, trains, and subways a long time ago, before we had electronic money like credit cards or phone payments.
The people in the American Vecturist Association like to share what they know about these transportation tokens, and they have meetings and events where they get to show off their collections and learn from each other. It's like a big club for people who really enjoy learning about and collecting a certain type of neat thing!
