The mini-sheet on this cover was issued in 2009 to celebrate the 38th World Cup of Baseball.
The 2009 Baseball World Cup was an international baseball tournament that started on September 9, 2009. The final was held in Nettuno, Italy on 27 September 2009. It was the first time that it was hosted by a continent rather than a single country. Eight European countries hosted the tournament and 22 nations competed, including defending champions the United States.
In the end, the United States won their second consecutive and fourth World Cup, over a win against runner-up Cuba.
