Thought I would toss this out there. Please see the pics. Rootbeer on left is a flat top. The other three cans are pull tabs. The rootbeer pull tab face has less coloring. Now look at the colas. Exact same can to a “T” but the face on the right is darker like the flat top. So I guess the questions would be is this correct or do you think maybe they had some flat top cola sheets left when they started to produce pull tabs so they used the darker colored sheets till they ran out. If that is the case would that mean this can is rarer than the other?

Interesting coloring variation. Not surprising as they started with the yellow haired version. Will have to look at the pics I’ve collected.
