Free Avatar and Userpic Pack
Free Avatar and Userpic Pack is a free Various design resource made by Dribbble user Robert Mayer. As far as I can tell, its license is Unknown.
Helpful hint: Dribbble users are nice. If the license is unknown, it is usually because they forgot to mention it explicitly; not because they were being stingy. Ask nicely and they will probably allow you to use it.
