My Grandpa Bill Luedtke raised Hereford cattle. Here's my graphite pencil sketch of one of them. I can see that I'm getting better at drawing these animals. The heads still are confounding for me. Practice, practice, I tell myself.
And here is the source photo, from a slide taken by my dad, Stan Hayes, and scanned by my sister MB. The photo is probably from the fifties. And that is one beefy cow!
