Though at this time the exact episode is not indicated here, if it becomes available, it will be added to the item's description at the bottom of the listing.

On Thursday nights between 1984 and 1992, millions of Americans in record-setting numbers spent the evening with the Huxtables. Via The Cosby Show, Bill Cosby brought us a message of hope and love that continues to connect with new generations of viewers worldwide. One of the most emblematic and iconic elements of the show was not something that was said or done. It was worn.

What was it going to be this week? Grandmother's quilt? A geometry professor's daydream? A telescopic image of the distant galaxies? We were fascinated by the sweaters that Bill Cosby wore on the show. In fact, the Cosby sweater is in our popular language as an expression meaning "multi-colored with vivid patterns."

Bill Cosby's sweaters have never before been made available to the public. The sweaters were custom made by Koos Van Den Akker, and only his designer label appears with no size marking indicated. They are approximately size large. The one-of-a-kind sweaters were specifically designed for Bill Cosby and are collages primarily composed of woolens and cottons.

All proceeds from the sale of this legendary Heathcliff Huxtable sweater will benefit the Hello Friend/Ennis William Cosby Foundation. The non-profit educational organization was established in 1997 by the Cosby family to continue the legacy and life's work of Ennis Cosby, who was about to begin his doctoral studies in education at the time of his death.

"My mother and father were going through a storage closet, and I happened to be there and pounced on these sweaters," explained Evin Cosby, who is a board member of Hello Friend. "I told them that the price of what some of these sweaters might sell for could make a big difference in the lives of thousands of children."

Hello Friend's mission is to equip teachers, parents and students with the practical information and educational tools required to understand and address the needs of all learners before they experience the corrosive effects of frustration and failure.
