An ex-model who appears in the opening credits of “Mad Men” is suing them for using her image from more than 40 years ago.

The Huffington Post says Gita Hall wants to be compensated for use of her picture, which, she asserts, helped make the sequence the key to the show’s success (huh?) and has “generated income in excess of $1 billion through exploitation of the series and its episodes.”

The face that launched a thousand clips! Good luck with that.
