This is a newspaper supplement from November 19th, 1950, a full 8 months before Alice in Wonderland was released in theaters. This image is just wrong in so many ways it is hard to count. Either that is one big caterpillar, or one tiny turkey. And the turkey looks like something right out of Regrettable Food.
As was standard with the newspaper supplements, there is no story inside about Alice, just a pretty picture on the cover (well, sort of). But the idea was to get people excited about the upcoming feature. And how could you be anything but excited once you saw this large insect larva serving up turkey.
