For your consideration ...
She wouldn't happen to have an ET as a souvenir would she? And a question ..... if a person makes a movie prop, who does the prop belong? The maker or the studios? How does that work?
She has a few small things, but her house is small enough that it become real cluttered, real quick.
As Lauren is basically an artist for hire, the studio owns what she makes.
Same with her husband Brian, though his most frequent clients are casinos.
One of his biggest clients has been the Excalibur, Lauren was also hired.
They get a royalty for every small replica of their work that is sold in the gift shop.
