Photo measures 9 x 7 in. From two days of testimony before the House Special Subcommittee on Legislative Oversight last week emerged the two faces of Bernard Goldfine. The first face, carefully shaped by lawyers and flacks (see box next page), was that of a humble, eager-to-please immigrant who had come to wealth and awakened astonished one day to find his name "in the newspapers all over America because of gifts and hospitality to a friend of almost 20 years." The second Goldfine told more about how he had become a millionaire in Massachusetts' tough, no-quarter textile and real estate world; that face was angry, the voice hard, the attitude belligerent, the answers evasive. And at week's end it was hard to say which Bernard Goldfine had most hurt his greatest friend, White House Staff Chief Sherman Adams.
