Sometimes the work speaks for itself, so strongly, that no bells and whistles are required.
Scratchboard is something we do as kids in art class. Or, if we were in schools without imagination or supplies, we used crayons (black over colour) to create "scratch art." Scott McKeown and Christina Possubiuk create stunning work together.
I do not know them, my friend David Cooper showed me their site. Scott does many things, but one thing he does with breathtaking mastery is scratch art illustration. Christina is a designer in the theatre. Their website is called Punch and Judy.
