The Katzman Automatic Imaging Telescope (KAIT) at Lick Observatory observed GRB 021211 starting 108 s after the burst, among the earliest observations of an afterglow to date. The optical transient was seen at an unfiltered magnitude of 14.8, and faded to magnitude 20.2 over the next 2.5 hours. Our well-sampled light curve, consisting of 20 points in the first 10 minutes and a total of 30 observations in the first 2.5 hours after the GRB, clearly shows a break at t=12 minutes, with a power law decay index of -1.60 +/- 0.02 before the break and -0.96 +/- 0.04 after the break. We hypothesize that the data before the break are dominated by emission from the reverse shock, as was suggested for GRB 990123. These observations offer high temporal resolution of the early behavior of GRB 021211 and are the first which directly show an early-time break.
