Tonight we have yet another set of unreleased sneak peek FarmVille images. This adorable Autumn Cow and Autumn Calf have been brought to our attention. We've been seeing a ton of Thanksgiving and Autumn items in FarmVIlle this season, and we're sure there are a few more releases before Autumn is over.

As usual, these items may or may not actually make it into FarmVille, but generally we have a pretty good track record when it comes to unreleased items.
