A while back, there was a thread seeking the identity of the actress who appeared in the Mitsubishi Galant 'Art Girl' tv ad, and in ads for Miller Genuine Draft, Thomasville Furnishings, etc.
I think we may have made an identification. Thanks to the film 'Vanilla Sky' and the detective work of Meredith Finegold, we believe it is a model/actress named Oona Hart, represented by Ford in LA.
Let me know if you hear differently; otherwise, the search may be over.
