Photo: Hadar reconstruction from the North Carolina School of Science and Mathematics
The North Carolina School of Science and Mathematics (NCSSM) is a science-focused high school. They have put on Flickr a large series of Creative Commons (CC-BY-SA-NC) licensed photos of their cast collection, including skulls of many hominins. I find it awesome to see a public high school taking this initiative, and I really appreciate the work behind this. Here’s a photo of the old Hadar A. afarensis reconstruction from their collection.

Their photos are also available at their school’s webpage, including the ability to render them as 3-D rotations.
