The David Tennant Treat 4 Today is the original photo of David Tennant for the poster for Hamlet.
The RSC have a policy of making a generic poster for each production which is usually prepared before rehearsals start so the company does not always know which costume the actor will wear. That's why David is wearing this coat which he didn't actually wear on stage.
David's picture was in the style of Caspar David Friedrich's painting The Wanderer Above The Mists but the original version released (reproduced below) clearly showed David standing on a step! This was airbrushed out of later versions of the poster.
However most fans preferred the poster from the same shoot which was placed outside the upstairs ladies loo at The Courtyard Theatre!
