“Cotopaxi”, DW painting from 1991

I just got a note from an appraiser who wanted to know what this painting of mine is worth. It’s in a collection and the owner wants to update their insurance. I have no idea! But it was fun to see it after so long.

Title: Cotopaxi
Medium: Oil on paper mounted on canvas
Date: 1991
Size: 30 by 44 inches
