Here's a soft, inviting picture of Shaun Casey from her stint as a spokesmodel for Estée Lauder in the early eighties. For the record, this comes from a 1982 print ad.
She was under contract concurrently with Karen Graham, the first time (but not the only time) the Lauder company used more than one spokesmodel simultaneously.
Check out her role as the girlfriend of Tony Lacey (played by Paul Simon) in Woody Allen's Annie Hall. As I'm sure I noted before, she got more time on screen and more lines than two extras who went on to bigger things - Jeff Goldblum and Sigourney Weaver.
