Zipper Loop is the most widely available oil lamp in classic Carnival Glass. It is found in marigold and smoke in a variety of base diameters, heights, and base sizes ranging from 4 inches to 6 1/2 inches. Size seems to make little difference in value. Collectors appear to choose lamps with better iridescence regardless of size. The finger lamp, shown at left in photo, are particularly desirable. Zipper Loop was reissued by Imperial in both marigold and smoke, with the IG mark part way up the inside of the base.
