A common practice with artists is to do preliminary drawings and sketches for planning an oil painting.  Sometimes several similar views are done to enable chosing the best one to paint.

I have generally only offered oil paintings for purchase, but I am going to start listing for sale some studies, charcoal and graphite of the Happy Cow paintings, as well as others.
I think they would make great gifts for any Holstein fan, especially if they love the Happy Cows. 

This is one of my favorites of the Happy Cows:
You may recognize it as California Is The Place To Be.  This is
graphite on Arches 90 lb hot press watercolor paper, a surface I am
especially fond of drawing on.  This is about 5.5"x7".

I love the value studies, hope you will too.  I'll be posting more as I  have time,
but commissions are calling!
