OLD MASTERS UNDERPAINTING: GRISAILLE: A CONTEMPORARY GUIDE TO UNDERPAINTINGS AND LAYERING FOR BEGINNERS Paperback – Large Print, 3 April 2023

I have to acknowledge that the content of this publication is helpful. BUT this is an anorexic book, scarcely more than a pamphlet, that hardly seems value for money.Also as I am not a possessor of a smartphone the continued use of the little square link things to access additional information is nothing short of infuriating. So I cannot award more than 3 stars.
