Birthday Bush is a 'man of heel'
Former US President George HW Bush is showing off his love for colourful, outlandish footwear by donning Superman socks to celebrate his 89th birthday.
Mr Bush spent the day with his family at their summer home in Kennebunkport, Maine.
A birthday photo released by his office in Houston shows a smiling Mr Bush on a golf cart, wearing red and blue socks with the DC Entertainment comic hero logo - complete with tiny capes on the back.
The 41st president has in past years marked his birthday with stunts such as skydiving.
But he has had medical problems this year, and spent nearly two months in a Houston hospital with a bronchitis-related cough before being discharged in January.
His wife, Barbara, turned 88 last Saturday.
