There is a black-and white photo on Andie’s bedroom wall to the left of her window seat (not her left, the viewers’ left). It looks like a fashion photo or something. Does anyone know who it is of? There appears to be a faint signature in the upper left corner of the photo, like an autograph or something. Thank you.

It looks like a photo from the 1930's, but without more info it would be hard to track it down.

Here is Ringwald's twitter page maybe she can answer your question?
