Famous quotes containing the words elevation and/or model:

    Understanding the spirit of our institutions to aim at the elevation of man, I am opposed to whatever tends to degrade them.
    Abraham Lincoln (1809–1865)

    I had a wonderful job. I worked for a big model agency in Manhattan.... When I got on the subway to go to work, it was like traveling into another world. Oh, the shops were beautiful, we had Bergdorf’s, Bendel’s, Bonwit’s, DePinna. The women wore hats and gloves. Another world. At home, it was cooking, cleaning, taking care of the kids, going to PTA, Girl Scouts. But when I got into the office, everything was different, I was different.
    Estelle Shuster (b. c. 1923)
