File-This April, 24, 2006, file photo shows former President Bill Clinton, left, looking up at his portrait after Lawrence M. Small, secretary of the Smithsonian Institution, right, helped him remove the drape at the Smithsonian Castle Building in Washington. A Philadelphia artist says that his museum portrait of former President Clinton contains a shadow reference to Monica Lewinsky’s infamous blue dress. Nelson Shanks tells the Philadelphia Daily News that a shadow beside Clinton is a literal reference to the dress and a symbolic nod to the shadow the affair cast on his presidency. (AP Photo/Haraz N.
