Here's the last page of a contract Joan Bennett signed in 1962. From whence I stole it claims that her Hancock ensures, "she will perform in a series of etiquette segments to which rights have been acquired from the Emily Post Institute." Okay, whatever that means.
But look closely at section 16, fifth line where it reads, "...our respective hairs, executors.."
I've heard of companies watching out for their interests, but really! And yes, the other signature might very well be that of noted publicist turned producer Jean Dalrymple.
