Wow, these are really good. I made a website to help colorize photos since I don't have photoshop. It's http://www.colorizephoto.com if you want to try yourself.
Dude, thanks for posting this. My uncle just gave me some black and whites of my dad and I know he is going to flip to see them in color. Just never thought about it before I saw this, cool.
A sure way to kill several hours coloring old family pics :)
