Agencies don't return emails and phone calls from random young creatives looking for work. They do return emails and phone calls from potential clients.
August Laustsen, a young Danish art director looking for agency work in Sweden, was having no luck in his job search. He had contacted all the big agencies in Stockholm, but didn't get a single reply.
So, he decided to fake them out a little. He pretended to be a client looking for an agency. (As you can see from the photo above, he's a multitasker of a client, too.)
