Freebie – Presentation Woman
Freebie – Presentation Woman is a free Illustration design resource made by Dribbble user Youssef Bousetta. As far as I can tell, its license is Custom License.
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.
