Tweedledee and Tweedledum up next, and once again we have some interesting details about these guys.
First, and most obvious, they are the same figure just with a stenciled name on the collar to distinguish them. This name is also applied over-glaze, like the White Rabbit's heart from yesterday. Also, most likely because of the whole "can't have a true red color" issue, their color is a little odd. In the film they sport a vivid yellow and red color scheme, but here that red has been muted down to a sort of dull maroon. I'm pretty sure this was so they could paint the majority of this figure under-glaze.
