Of apples and apple trees

My father drew this in... 1966? It recently came to light in the collection of an old football buddy of his from college. He doesn't know it exists as I write this and probably won't see it until he opens his email tomorrow. I think it's amazing, although he might want me to mention that he spent considerably more time and care on some later efforts, which might also be worth a blog post at some point. But anyway... today is his birthday. Happy birthday, dad.
