The Wallace and Gromit grand day out has finally arrived.

Today more than 300 lucky Evening Post readers will head down to At-Bristol to help celebrate the duo's 20th birthday after discovering 'golden tickets' in last week's paper.

Those who didn't get a ticket should take a chair – and umbrella if it's raining – down to Millennium Square where all the Wallace and Gromit films will be screened for free.

The pals will also make a guest appearance to sign autographs and pose for pictures with their fans.

The At-Bristol cafe is also open to everyone and will be serving special Wallace and Gromit snacks to raise money for the Children's Hospital.

Those with tickets can look forward to a series of workshops in character building, model-making and story-boarding led by Aardman animators.

They can also watch digitally re-mastered screenings of A Grand Day Out – the dynamic duo's first adventure – in the centre's planetarium and get the chance to try all the exhibits at the Animate It! show.

There will also be a chance to buy a limited number of copies of new book, The Art of Wallace and Gromit, signed by Nick Park, which will be available in the centre's bookshop.

For those who can't make it down to the event, the celebrations continue with a talk on the much-loved pair. As part of the Festival of Ideas, a host of speakers, including Sir Christopher Frayling, former Rector of the Royal College of Art and past chairman of Arts Council, England, will show clips and lead discussions on the much-loved characters at At-Bristol on December 3 from 7pm to 9pm.

Tickets cost £7.50/£6.00 and can be bought from At-Bristol. www.ideasfestival.co.uk.
