Jeopardy! host Alex Trebek is being posthumously honoured with a U.S. postage stamp.

A sheet of stamps featuring the legendary Sudbury, Ont., born quiz show host was unveiled on Monday, timed for what would've been his 84th birthday.

It's designed to evoke the TV studio of Jeopardy! with an archival photograph of Trebek standing beside a wall of the game show's trademark screens, with headers that read "Entertainment," "Game Show Hosts," and "Famous Alexes."

Underneath each header is a row of stamps — resembling the show's famed blue screens — offering the same clue: "This naturalized U.S. citizen hosted the quiz show 'Jeopardy!' for 37 seasons."

The answer is written upside down across the bottom of the stamps: "Who is Alex Trebek?"

The United States Postal Service launched the stamp to honour the show's 60th anniversary during an event at the Sony Pictures Studios lot in Culver City, Calif.
