Thank you!
Wow. Michael! Thank you for your very quick response!
And I'm sorry; I thought I was starting a new thread. Oh well, I guess we may as well stick with this one, since we're here.
I am certain that the design was NOT patented. Diane never did "official" things like that, and was much too prolific an artist to ever go through that much paperwork.
Are you saying, then, that who(m)ever took the photo, owns the copyright? That's not good (or fair!) ...

-head probably did that himself, or had someone else do it for him...
And then ... on whose behalf would the suit be filed? I don't think she left any kind of will, and she had no children, or legal spouse --depending on the state, I presume.
In the event of a financial settlement, who would be the beneficiary, besides the European attorney?
Well, actually that doesn't matter.
Thanks very much! You have been most helpful!!
