Williams’ Golden Globe Awards for Mork And Mindy, Good Morning Vietnam, The Fisher King and Mrs Doubtfire are also among the lots going under the hammer.

The collection features a watercolour from the set of Good Will Hunting which was painted by the film’s director Gus Van Sant and inscribed to Williams.

The picture was displayed in the office of Williams’ therapist character Sean Maguire and served as the focal point of Will Hunting’s first therapy session with Sean.
