Harvard Crimson (1972)

It appears Harvard had a difficult time figuring out how to decorate its headgear in 1972, as the Crimson burned through two different number fonts before a mid-season switch to a big, fat generic "H," which was used through '73. The block font, which had been used since the early '60s, was interchanged with a rounder font in '72 only before the change to the H.

This 1973 Harvard-UMass program, from a 1972 game, shows the numbered

The era of numbers on helmets was ending by this time, save for traditionalists such as Alabama. Of the 18 Division I teams in the project for whom I have records, 10 wore numbers on their helmets in 1962; only three still wore numbers a decade later -- Harvard, Maine and New Hampshire (which was the only team to actually add numbers over the previous decade).

One other thing about this Harvard uniform: I like how the socks coordinate with the jersey, with crimson socks at home and white socks on the road. The Patriots do something similar now, but that likely has more to do with making them contrast better with the blue road pants, whereas Harvard wore the same color pants home and away.
