The public will get a glimpse of more of former President George W. Bush's artwork this spring in a new exhibit at the George W. Bush Presidential Library and Museum.

The presidential library this April is opening "The Art of Leadership: A President's Personal Diplomacy," which the Dallas Morning News reports, will focus on Mr. Bush's relationships with world leaders. The exhibit will feature two dozen portraits painted by Mr. Bush that have never before been on display.

The former president took up painting after leaving the White House. Last year, he released a painting of his beloved dog Barney after the 12-year-old Scottish Terrier died. Over the holidays, the George W. Bush Presidential Center released aChristmas ornament that featured one of Mr. Bush's works -- an untitled painting of a cardinal.

In April, Mr. Bush told "CBS This Morning" host Charlie Rose that he paints between two to three hours a day and was considering what colors he'd use to depict the anchor's tie.

"It's a joy. It really is a joy," Mr. Bush said. "And it's a good lesson. You know, what I learned from my dad is, you know, my dad never stopped living. He jumped out of airplanes at a ripe old age of 85. You can teach an old dog new tricks and I'm learning."
