The world is full of people making woodcuts and signing them and framing them and assembling collages and framing them. Think of all the universities that have art departments and offer advanced degrees, and add all the small art schools around the world....and all the matures.
There is a tremendous amount of "art" out there by people who are not "famous".
If you can't find the names in a data base I would assume you have something of that sort.
If you like them, hang and enjoy.

Google "Carol Goodkind". She's there.

Solved? Google does not give me a "Carol Goodkind artist" - only that a person has that name.

she can contact the person by that name in several ways, such as facebook, and ask directly.

There are hundreds of persons with that name....no way to contact anyone who just perhaps might be a collage artist.
Problem is not solved.

I give.

In my view, this is a silk screen print. I googled her name and silkscreen artist and got the listing below. You probably have to subscribe to the paper to read the article. She may or may not have her work at the Museum. Her name may appear in an article printed near the first. Anyway, it's a place to start.
