A series of materials to promote the political party conferences taking place has been developed by 999 Design, alongside the Guardian and Observer newspapers.

The materials aim to convey the idea of the blurring of political boundaries, triggered by the coalition Government, using a handcrafted watercolour theme, which will be used to promote the Guardian debates and Observer interviews featuring representatives from the three main parties.

999 Design was appointed by Guardian News & Media earlier this year following the publisher’s decision to outsource the production and delivery of its events marketing, advertising and sales support design and presentation work.

999 was also responsible for designing drinks reception invitations for each individual party and for applying design to room dressing for each of the three receptions held by the parties post debate.

Aileen Geraghty, managing director at 999, said: “This is one of many creative pieces of work that we are proud to be delivering for The Guardian since our appointment. We created the watercolour theme to deliver an overarching look and feel and to really strengthen the brand presence at all three party conferences. This creative works hard to make the messaging stand out and to reinforce the Guardian and Observer brands throughout all the materials. For the invitations specifically, we selected a beautiful paper to ensure that we did the watercolour justice and we’re all delighted with the results.

“It is something a little different and it creates a really strong identity for each of the events that is immediately memorable and recognisable.”
