Mystery Client

It's not often that I have no clue who I'm making an illustration for...but this is one of those cases. I was contacted by an agency who handles the art direction for multiple magazines. I was told the illustration was for an article about teachers who are resist change in the classroom. That's it. I have no idea when this was published or where it was published, and many attempts to find out how have yielded no information whatsoever. I can't complain, though; it was an enjoyable project and I was treated fairly. Still, part of me wonders if this illustration was for something top secret...
