Cheerful Christmas tree ornaments dangle from the cross-bracing of a well-engineered bridge or abstract architectural structure, on the front of this holiday greeting card. Each ornament is surrounded by a glowing golden filigree, wrought in a shape perhaps reminiscent of the star of David, or of the shape of the Earth. Each ornament has at its center a glowing ball of corporate blue. The lower right hand corner is a rich holiday maroon, with a “Season’s Greetings” message fit to the shape of the curve. Corporate drab and blue colors complete the tasteful color palette. Engineer your way to holiday cheer with this architectural holiday card.
