A plea or a gripe-depends where you are

This is a plea which may well sound inconsequential or not worth bothering about and may well bring down the wrath of God on my head but..........

To everyone who designs/makes-up/is responsible for Posters

Please. Please PLEASE include the year of production in your designs.

Now this may sound obvious/trite/not worth bothering about BUT I do assure you that in time to come when some poor soul is trying to make sense of the archives (which are usually in a mess when some  brave person decides to get them in some kind of order) it saves much frustration and hair-pulling out.

And this is where I get myself into more trouble- the design is not as important as the basic information-WHAT-WHERE-WHEN-HOW MUCH-WHERE DO I GET TICKETS

OK off my soap-box
