What is the name of the group that provides Marty with the ever-important flyer that encourages him to help "save the clock tower"?

The Hill Valley Preservation Society plays an important role in the movies, providing Marty the flyer that reminds him of the lightning strike used to send him back to the future. It's also used by Jennifer to write down her grandma's telephone number, along with "I love you!" on the back of it.
