As many as 50,000 people marched in the funeral procession for King, his casket carried by a mule-driven farm cart, symbolizing his support of the rights of poor people.

Rich wore this button, having helped to organize the labor contingent at the funeral.

The text of the button reads:

I HAVE A DREAM

LET FREEDOM RING

A GREAT AMERICAN

REV. MARTIN LUTHER KING
