Great Unitas run!

I never noticed this before and forgive my ignorance if this has been discussed previously but are the 1973 & 1974 Unitas cards from the same photos, or not identical photos but those in the same few negatives as the camera was moved? I have not had a drink today , but it seems the cloud in the background is the same, though he's in a Colts uni in one and Chargers uni in the other, I'm pretty sure that's not Unitas' waist in 1974. He also seems to be wearing the same threadbare undershirt at the sleeves.
