DescriptionSanta Lights. Distributed by Universal Folding Box Co., Inc., Hoboken, N.J. No date, circa 1949-1953. Printed box with die-cut top, overall: 5-1/2" deep x 10-1/2" wide x 1-1/2" high; contents: 7 light string of lamps (candelabra base), fresh and unused, plus 4 other bulbs of the same type showing some usage; printed round Underwriters Laboratory tag threaded on wire (by factory) near female plug end.

For a Bright and Festive Holiday. For Indoor Use Only. Top is die-cut and designed for box to be displayed open, showing the contents for retail store or window display. Universal was apparently the box maker and distributor of this Christmas holiday decoration product. The Underwriters Laboratory (UL) tag on the light string for " Xmas Tree Light Outfits " indicates the lighting string itself was made by Idalite, Catalogue No. 1000. The light string itself was innovative for the "Pin-tap Lamp Socket". The molded case of the female plug has "Gilbert", "Patent Pending". This would indicate the date range for the manufacture and likely distribution of the product. A patent was applied for by Charles E. Gilbert on Jan. 4, 1949 with U.S. Patent 2,636,069 issued to him (by then deceased) on April 21, 1953. PDF of this patent is on file.
