Well, not a holstein exactly, but might do.
Try doing a Google search "embroidery holstein cow pes"
The pes makes sure you don't just get pictures of a cow.
EmbroideryDesigns has several realistic cows. You could just do the head part.
I have 2 different sets of cows and the way they stitch out, it would be almost impossible.
You could also ask Vickie at basketkase to dig. one for you? She does great work.
Country Cow Square at emblibrary could be done without stitching out the frame? Give it a look.
