Irn-Bru has celebrated 30 years of its longest running and most iconic campaign - Made in Scotland from Girders - by projecting images of special commemorative bottle designs onto the Forth Rail Bridge.

The five limited edition pack designs, showcasing the brand’s most nostalgic and loved advertising posters, will be available for six weeks only.

Irn-Bru spokesman Adrian Troy says projecting the design onto the world heritage site was a fitting tribute.

“The Forth Rail Bridge and girders are engrained into IRN-BRU’s history, from the famous ‘Rail Bridge’ poster to the opening ceremony of the Glasgow 2014 Commonwealth Games, so it felt right that we include it in our celebrations with this unique projection,” he said. “Plus, we all know IRN-BRU is actually made from Girders…”

Irn-Bru, first brewed in Scotland more than 100 years ago, is now sold across the UK.
