The term 'Lincoln Trademark' is associated with two iconic features of the 16th President of the United States, Abraham Lincoln. The first is his famous STOVEPIPE hat, which was a tall, cylindrical hat made of black silk and worn by Lincoln during his presidency. The second is his iconic BEARD, which he grew in 1860 and kept for the rest of his life. Both of these features have become synonymous with Lincoln's legacy and are now known as the 'Lincoln Trademark'.
