"The Art of Leadership: A President's Personal Diplomacy" will open in April and will feature over two dozen artworks by Bush, who took up painting after he left the White House, the Dallas Morning News reported.
The library, on the campus of Southern Methodist University, did not specify the subjects of the portraiture, but said the exhibit "will provide an insider's view into President Bush's unique relationship with other world leaders."
In an April 2013 interview, Bush, who signs his paintings "43," said he took "great delight in busting stereotypes" people have about him.
"People are surprised," he said. "Of course, some people are surprised I can even read."
