Artist David Foster has nailed some of the most iconic celebrities in Hollywood. From Mick Jagger and Marilyn Monroe to Beatles legend, John Lennon, he’s done them all, creatively using between 5,000 and 35,000 nails to hammer together intricate portraits of their complex faces. After suffering ill health 12 years ago, Foster gave up his career as an architectural technician to pursue art, but knew he had bring something fresh to the table. “I had to come up with a twist,” the 52-year-old from St. Helens, England, wrote to GoodMorningAmerica.com. “I literally 'hit the nail on the head' and experimented with using nails.” Each portrait takes about three weeks to make, and one of the Queen with Prince Andrew based off a 1960 photograph has earned him acclaim from the Victoria & Albert Museum. “They were thrilled with the result,” Foster wrote.
