Totally agree with the above. It baffles me when the year of the production doesn't feature on the poster. Ditto with the cast list as I mentioned earlier. It's always much more interesting when you come across an old poster years down the line and are reminded who was in the show.
Thanks for flagging this up. I have a real interest in theatre graphic design. I love looking at theatre posters but dislike the modern trend of leaving off cast and crew info- the National ones in particular but some West End ones too.
I remember a very good production at the Piccadilly with Timothy West and Prunella Scales in the late 90s, but I didn't see the later production at the Duchess with Eileen Atkins and Henry Goodman. Good to see it being revived again by Sonia Friedman.
