The Tinkers' Black Armbands

Origin
The Tinker siblings decided to wear black armbands to school to protest U.S. involvement in the Vietnam War. They were suspended, but then the Iowa Civil Liberties Union convinced them to sue. After appealing the court ruling all the way to the supreme court, it was ruled that the Tinkers did have the constitutional right to symbolic speech through clothing.

Usage
When worn, the user's cause will gain national attention, while also bringing scorn from opposing authority figures.

Collection
Claudia and Steve collected these five armbands the day before U.S. Supreme court ruled that same-sex marriage is to be recognized in all states. Whether or not the protesters wearing the armbands knew of the effects is unknown, but neither of them have complained about the outcome.
