WATCH: Ravens spread word about Game Of Thrones event

Organisers of Chicago Humanities Festival decided there was only one way to spread the word about Game of Thrones author George R. R. Martin – who they’d booked to speak.

The world’s first-ever direct mail campaign delivered by Raven.

In a film shared by the author on Twitter the birds can be seen flying off with tiny scrolls in their beaks, being captured on CCTV, and even landing in a TV newsroom.

“We’re sending invitations in true GoT style: by raven,” he tweeted. “Next week, be sure to look. You may just see some feathered friends delivering scrolls all over town.”
