Patriotism Is Supporting Your Country All The Time, & Your Government When It Deserves It. --Mark Twain. Postcard Recycled Paper. Text from the back side of this postcard reads: Most US histories ignore the fact that Mark Twain (1835-1910), author of Huckleberry Finn and Tom Sawyer, was an outspoken anti-imperialist & anti-capitalist as well as a humorist, satirist and lecturer. The following information is NOT printed on this postcard: Samuel Langhorne Clemens (1835 – 1910), well-known by his pen name Mark Twain, was an American author and humorist. Twain is noted for his novels Adventures of Huckleberry Finn (1884), which has been called "the Great American Novel", and The Adventures of Tom Sawyer (1876). He is extensively quoted. Twain was a friend to presidents, artists, industrialists, and European royalty. Twain was very popular, and his keen wit and incisive satire earned praise from both critics and peers. Upon his death he was lauded as the "greatest American humorist of his age", and William Faulkner called Twain "the father of American literature".
