LEGO and cardboard were this year’s inspiration. The basic forms of the tree were replicated from LEGO set 10069 (a Christmas tree). A full explanation is at Flickr along with hi-res images. The original LEGO set was about 3″ tall. My cardboard version was about 18″ tall. The reverse side of the card featured a photo of the LEGO set with a grayed out cardboard tree.
