More than 5,000 poster sites across the UK from now until April 23 will be highlighting Bombardier “as the heart of everything positive about Englishness”.
The ads put Bombardier at the centre of a coat of arms comprising numerous English icons including Queen Victoria, pork pies and Les Dawson.
The posters also highlight Bombardier’s sponsorship of English Heritage as its official beer.
Marketing director Chris Lewis said: “Bombardier has ‘owned’ St George’s Day for the past 15 years.
“We have the great problem every year making St George’s Day bigger than the previous year and generating more sales for our stockists.
“Beginning our advertising campaign much earlier this year means Bombardier will be at the front of consumers’ minds.”
