Eggs for Soldiers is an ongoing fundraiser that gives a percentage of their free-range eggs sales directly to Help for Heroes, an organization providing direct support to wounded soldiers. In an effort to support the organizations' March Fourth 2013 campaign, artists Jack Munro and Charlotte Austen built an aircraft completely out of the charitable egg cartons. Modeled after a Mark I Spitfire, a British single-seat fighter aircraft that was used during the Second World War, the piece stands approximately 40 feet long and 42.5 feet wide.
Across the course of 6 weeks, Munro and Austen constructed the life-size model out timber and steel framing, and covered the structure first with canvas, then with 6,500 egg boxes, 1.5 gallons of glue, 5,000 nails, 2.5 gallons of paint, and 10,000 staples. Munro said, “The biggest challenge in building the structure of the Eggs for Soldiers Spitfire was to recreate the plane's iconic but complex geometry as accurately as possible.” The piece was recently unveiled at the Imperial War Museum in Duxford and stands alongside many other classic aircrafts.
