Hi Everyone--thanks again for the comments. It's always nice to get feedback from others.
This picture looked like a good place to start for me. Luckily the original was in good condition so that made the job easier. My dad lives in the middle of no-where in the upper peninsula of Michigan. I emailed the picture to him (actually to his wife who is much more computer-literate). His response was, "Hey! Who is that
kid? I think I remember him from somewhere!"
That photo definitely captures the essence of my father. The current version is just as handsome, IMHO, but with a little less hair.
P.S. Doug, does this mean I don't get to wish you Happy Birthday?
