One of the middle-period Thomas Glenn Holidays designs was the "squares" pattern.  They were done in a variety of colorations, but this one - multi-colored - combines red, green, gold, and silver squares around the surface of the ornament.  Now retired, only one of the multi-colored examples is still available - and once it has sold - it will be removed from the website. Side, top, and bottom views are shown here.
