The College Football Centennial Logo

There is a general consensus among historians who study the sport of American football to recognize a game played November 6, 1869 between teams from Princeton and Rutgers as the "first college football game". One hundred years later, during the fall of 1969, the football teams at Princeton, Rutgers, and many other colleges commemorated this centennial by wearing on their helmets a special decal depicting the numerals "100" inside a football-shape. Some teams apparently used the "100" decals for only a single game, while others wore them throughout the season; usually these decals were placed prominently on the sides of the helmets, in place of the respective teams' usual helmet decals.

These "100" decals have posed a particular challenge to the completion of historical helmet images at this web site, because I have received very few good photographs of them, and because there were significant differences between the versions used by the various teams. Note the substantial differences in shape between the versions used by Rutgers and Northern Illinois:

Additionally, the decals were produced in at least several different colors, which sometimes did not coincide with the official colors of the team wearing them. Nebraska, for example, used a blue football-shape, as did both Bowling Green and Washington State. Rutgers used a gold or yellow football-shape. Sometimes the numerals "100" were outlined in a third color, which again was sometimes inconsistent with the team's official colors.

While most teams wore these decals on the sides of their helmets, several teams wore them at the back of the helmet:

At least two teams (Nebraska and Yale) wore the "100" decal at the front of the helmet:

Below are some more of the clearest photographs I have received showing the detail within the "100" decals:

Following is a table listing the colleges known to have used the "100" logo during at least one game in 1969 - there were probably many others, and I would appreciate additional reports (including for small colleges).

Does anyone know of an existing, game-worn helmet from the year 1969 featuring one of these original decals? (One is reported to be at Princeton, see note in table above, and another in the possesion of a former Syracuse player, see note in Syracuse section).

Might we expect to see some "150" decals during the fall of 2019?
