The company's latest score is David Beckham.
"Beckham, whose autograph is among the most sought-after in the world, will become Sharpie's global ambassador in a fully integrated global marketing campaign that rolls out initially in the U.S. in early March," the company says.
Details about the Sharpie-Beckham campaign, which will include print and online advertising, are to be announced in May.
Sharpie is owned by Atlanta-based Newell Rubbermaid.
