Former President George H.W. Bush honored his wife's work promoting literacy with a subtle fashion statement: socks covered in books.
The nation's 41st president attended his wife's funeral on Saturday in a dark suit and black shoes. But peeking out in between were knitted stacks of blue, red and yellow books.
Family spokesman Jim McGrath tweeted a photo of the former president's attire. He says Bush wanted to honor his wife's commitment to family literacy during her life.

McGrath says Barbara Bush "raised over $110 million over the course of 30 years" for literacy programs.
The former president is known for wearing colorful socks. He and his wife had been married for 73 years when she died on Tuesday at age 92.
