Quoting myself, I don't count the one with just a small band of white as the white bottom, these two mugs, the bottoms are obviously different. The one with the white bottom is from last fall, the one with the design all the way down is from this April.
I hate the current mugs!!!! I didn't buy one last December because they would never fit in our cupholders. I like the old design. The handle on the new one comes down too far. What do people have? Gorilla hands? ACK! Now to hear that they'll be the same old mugs THIS December does not make me happy. Two trips twelve months apart should get me two different mugs.
