'83 bears vs san fran 49ers

I am guessing but I think it was the '85 bears that one it all but I could be wrong I did not get a chance to look at this footage in all its gritty goodness but you will hopefully. I think these are Mr. Joe Montanas early years under center if he is even out there at all with a Mr McMahon under center for the bears. This will be a good game...
