LOS ANGELES （Reuters） - Photographer Greta Pratt knew she hit the jackpot（头彩）when the nine Abraham Lincolns sat down on the wood fence outside the 16th president's old Kentucky home.
Nine unsmiling, bearded Lincoln impersonators（模仿者）, with black stovepipe hats（大礼帽）, starched（笔挺的）white shirts, black ties and long, black frock（外衣）coats arguing over which one was the most authentic（可信的）—— you can't ask for anything more in Pratt's world.
Unless, of course, it's the cleaning lady pushing her vacuum cleaner（真空吸尘器）past the concrete tee-pees（印第安人的圆形帐篷）at the Wigwam Motel in Holbrook, Arizona, or tourists downing fries and Cokes at the picnic tables nestled（舒适地坐定）among rockets at the Kennedy Space Center.
Or it might be boys in baseball caps begging Gen. George C. Custer for his autograph（签名）, perhaps before he rides off to his doom in a re-enactment of the battle at Little Big Horn.
Pratt's photographic universe is actually an intersection（交叉点）—— the place where the American past slams into（撞击进入）the American present. And it is on full display in her new book of photos called "Using History" .
In the book, three generations of prosperous（富裕的）white males celebrate Thanksgiving dinner at the Rainbow Room in Manhattan's Rockefeller Center（洛克菲勒中心）wearing Brooks Brothers（布鲁克斯兄弟）suits, shirts and ties, all capped by little Indian headdresses（发式）. The dinner cost $120 a person, headdresses included.
A few pages later a green-tinted（带绿色的） Lady Liberty（自由女神）eats popcorn（爆米花）in the bleachers（运动场的露天看台）at Madison Square Garden. She is Jennifer Stewart, who once won a Statue of Liberty look-alike contest and started dressing as the statue and even went to Japan with New York Mayor Michael Bloomberg.
Pratt often uses clever juxtapositions of photos to tell her tale of how Americans incorporate their country's past to explain their attitudes to the present.
