The "Skull Bandana" wasn't actually intended to be a Thanksgiving bandana, rather an incentive to check out the new customization features. It was available from February 27, 2008 - the day the shops opened their doors - to March 2, 2008
The Golden Skull (red) bandana, was released as a part of the Founder's Feast and was available from November 27, 2008 to December 7, 2008. No evidence we'll get a bandana yet, or if we'll get anything at all.
Thanks to the wiki for this information and the images of both bandanas
