In two ad campaigns for the GAP, I have seen a model that looks exactly like my ex-girlfriend, and I would like to confirm if it is her or not. I do not keep in touch with her, and would feel weird calling her out of the blue just to ask. Nor do we have any mutual friends.
Is there a resource for confirming the name of the model?
Go to your local library (or use the internet) and read ad industry pubs. Find out what agency does the Gap ad. Call the agency and ask. Call several times until the phone is answered by a receptionist who will help you.
