Summit Notes: For more than 30 years, Howard (Mac) McNamara has been Duke Zeibert's bartender, and he doubles as the restaurant's official photographer. When sports celebrities and movie stars come into the restaurant, McNamara is always ready to take Zeibert's picture with them. Yesterday, like a professional journalist, McNamara ran for his camera when Mikhail Gorbachev surprised the lunchtime crowds at Connecticut and L by leaving his limousine and wading into the crowds to shake hands like a presidential hopeful. McNamara shot a roll of film from his unique balcony vantage point above the busy intersection, getting photographs professionals could only dream about. One is on the front page of today's Washington Post, and another is on the front page of Style. His once-in-a-lifetime photographs appear destined to run in publications around the world ...

Raisa Gorbachev's mix-and-match traveling wardrobe may have been the result of some fashion advice from Janet Wallach, Washington author and former fashion director at Garfinckel's. Wallach said yesterday that two months ago the Soviet Embassy requested copies of her recently published Viking book, "Looks That Work" and indicated that a copy was being sent to the Soviet first lady. "Her picture in the paper today was a perfect example of how a wardrobe can work. I think I was partially responsible and it feels good," Wallach said. Her book describes how career women can put a mix-and-match wardrobe together.

Nixon Opposes Eviction Plan

That blind, 93-year-old woman threatened with eviction from her home of 65 years to make way for the Richard M. Nixon Library won't have to leave after all. The former president says he remembers Edith Eichler from his boyhood days in Yorba Linda, Calif., where the $25 million library will be built, and asked that she be permitted to keep her home as long as she wants.

Eichler's home is the only residence in the nine-acre library complex. "We didn't even know the house was occupied, let alone by somebody who knew the Nixon family well," said John Whitaker, executive director of the library foundation. Nixon was born in Yorba Linda and spent the first nine years of his life there. "I knew the Nixon family very well, Eichler said. "Richard was a nice little boy, always running around like any other kid. Who would believe he would become president?"
