We present here the results of a study carried out at the Harvard College Observatory Plate Collection .
We examined 3995 plates covering the error box of the gamma-ray burst GRB 910122 , over a time span of 90 yr ( from 1889 to 1979 ) .
The total exposure time is \sim 0.55 yr. No convincing evidence of optical transient emission was found within the GRB 910122 IPN error box .
However , a possible OT was found outside the GRB 910122 error box .
Optical ground based observations have revealed a V \sim 22.3 object consistent with the position of the new object .
The colours of the object are typical of a K7/M0 star or a reddened galaxy , which could have caused the OT , but the fact that the object is far away from the GRB error box makes both events unrelated .
