Elsa Beskow was the illustrator that shaped my taste I think. The books my mother had loved as a child in Sweden were passed on to me and I poured over every detail and loved them too. --- I too Elsa Beskow.
I enjoy art on all types of Christmas cards, and no matter what genre they are, when they're done well, I can really relate to it. But possibly my favorite art on cards comes from the images on vintage Christmas cards, which not only sent a message.
