Below are contact cards I thought could work, using the border on the top right corner, and also using colours that relate to the art work in the corner in the typeface as well.
I want to include her work some how in the card as I think it brightens up the card and explores her artistic approach a little more. I have also noticed that her work is always on a frame, within a frame, square/rectangle format. There is a sense of neatness/restriction combined with large scale, blocky paint.
I also think the text has more clarity when on white as appose to over an image.
Applying to border to letterheads, order confirmation letter, compliments slip:
