That year was the 1st recorded game with rules played in Hoboken, NJ as the NY Nine beat the NY Knickerbockers 23-1 in 4 innings.
Since the NFL started in 1920 an the NY GIANTS established in 1925, the GIANTS have won the Championship 8 times. The Giants obviusly have 4 Super Bowl Rings from 1986, 1990, 2007 and 2011, but they also have NFL Championship rings from 1938 and 1956. They won the NFL Championship in 1927 and 1934 also, but there are no known photos of these rings onn the internet. There are photos of the Chicago Bears Championship ring from 1933 and championship rings were awared in 1927 to the NY Yankees, so somewhere there must be these rings in existance. To sum it up, the NY GIANTS have won eight World Championships and champions are awarded rings each year.
