The tan cow is by far the most common version.
There is a mold variation with three udders in a row rather than 4 in a square. It's unknown what sets it came in, but is probably the earlier mold variant.

There is also a darker version of caramel tan that is rarer, possibly from Schaper in the US an dother early sets. It comes in both variations.
The color variation is hard to tell in photos but is more obvious in person.
