The challenge is to create a graphic design and colourway for the Veuve Clicquot Mailbox. A shortlist of 18 designers will be invited to Veuve Clicquot's Hôtel du Marc, in the Champagne region of France, for a prestigious two-day experience.

An international jury of influential names in design will choose the winning mailbox design, and the selected the designer will be awarded an incredible €10,000 in prize money.

Sending in a mailbox design is easier than licking a stamp. Go to the wallpaper.com for all the information and tools necessary to submit a unique design.

Good luck!
