Famous quotes containing the word gallery:
“I never can pass by the Metropolitan Museum of Art in New York without thinking of it not as a gallery of living portraits but as a cemetery of tax-deductible wealth.”
—Lewis H. Lapham (b. 1935)
“It doesn’t matter that your painting is small. Kopecks are also small, but when a lot are put together they make a ruble. Each painting displayed in a gallery and each good book that makes it into a library, no matter how small they may be, serves a great cause: accretion of the national wealth.”
—Anton Pavlovich Chekhov (1860–1904)
“Each morning the manager of this gallery substituted some new picture, distinguished by more brilliant or harmonious coloring, for the old upon the walls.”
—Henry David Thoreau (1817–1862)
