Scarce 2-3/4 inch diameter clear plastic halo by Noma for the old, smaller C-6 size Christmas light bulbs - most were made for the larger C7 bulbs. The halos were used on lighted Christmas candoliers, angels, wreaths and tree top decorations in the 1940s and early 1950s. When placed above the bulb they create a glowing, soft halo effect to the light. The halo is in good vintage condition with no cracks or chips. There are some small scuffs and scratches from 70 years of use and storage.
