From her obituary in the New York Times, Sunday February 5, 2012:
Ms. Mulzac’s profession was selling books at Liberation Bookstore, a Harlem landmark that for four decades specialized in materials promoting black identity and black power. On one side of the front door, a sign declared,
“If you don’t know, learn.”
On the other:
“If you know, teach.”
Ms. Mulzac died at a hospital in Queens on January 21, at the age of 88.
