As part of the 9th annual Freedom Conference & Festival , a conservative confab taking place in Steamboat Springs next month , the paintings of 43rd President George W. Bush will be on display for attendees at the Steamboat Grand Hotel . 
"This is the first time the -LRB- Bush -RRB- exhibit has been shown in Colorado , giving state residents a unique opportunity to view this popular collection ," wrote Jackson Shedelbower , of the Steamboat Institute , in an email . 
The one-day exhibition on Friday , Aug. 25 , organized by the Steamboat Institute , marks the Colorado debut of Bush 's work from "The Art of Leadership : A President 's Personal Diplomacy" exhibition , which features paintings of world leaders Bush met during his tenure in the White House including Vladimir Putin , Angela Merkel , Hamid Karzai , Ellen Johnson Sirleaf and Tony Blair . 
Although some balked at the idea of Bush as a fine artist when he took up painting in his post-presidential retirement , the 71-year-old has stuck to his guns and humbly worked to improve his art . 
"Portraits of Courage : A Commander in Chief 's Tribute to America 's Warriors ," a book of Bush 's paintings of wounded U.S. military veterans that was published in February , netted surprisingly favorable reviews from critics and topped The Washington Post 's best-selling books list earlier this year . 
"-LRB- Bush -RRB- was really putting himself out there and taking a personal risk with these paintings , not knowing what people would think of them ," said Jennifer Schubert-Akin , CEO of the free-market , nonprofit Steamboat Institute . 
Bush will personalize a copy of the book that is being auctioned on the Steamboat Institute 's fundraiser as part of its $ 75-per-person Red , White & Blue Bash fundraiser on July 20 , Schubert-Akin said , with bidding starting at $ 300 .

Q: The heir to Saudi Arabiaâs throne has accused  Iran  of âdirect military aggressionâ which could be an âact of war â after Saudi air defense forces intercepted a ballistic missile on Saturday fired toward the capital  Riyadh  from across the border in Yemen.
Yemen has been embroiled in a civil war since 2015 between a Saudi-led military coalition in support of the Yemeni government  and Houthi rebels believed to be funded by  Iran .
âThe involvement of  Iran  in supplying missiles to the Houthis is a direct military aggression by the Iranian regime â the Saudi news agency SPA reported  Crown Prince Mohammed Bin Salman  as saying on Monday  âand may be considered an act of war against the Kingdom.â The language closely matched a statement earlier given by the Saudi-led coalition.
 Iran  immediately denied  it  was behind the missile launch.
The head of the Saudi military coalition said that experts in military technology had examined other missiles and âconfirmed the role of  Iran âs regime in manufacturing these missiles and smuggling them to the Houthi militias in Yemen for the purpose of attacking the Kingdom  its people  and vital interests.â
 The crown princeâs  reported remarks mark a new height in tensions between  Iran  and Saudi Arabia  the regionâs rival powers. The civil war in Yemen is widely seen to be a proxy war between the two countries  and has resulted in the deaths of over 10 000 civilians and triggered a humanitarian disaster including a cholera outbreak which has infected nearly a million people.
