Victorian Custard or Ivory Glass Argonaut Shell Set.  Made by Harry Northwood.  Circa 1900.   All pieces are signed on their bases with the Northwood Script.  The Set consists of a Creamer, Sugar (no lid) Covered Butter and a Spooner and they ALL GLOW under the Black Light. The gold is very good.  There is minor wear to the gold, but since the Set is over 100 years old, this is to be expected.  The decor, of green seaweed and gold shells which is at the base of all of the pieces, adds so much to the beauty of this Set. It is in Excellent Condition. It would make a nice Christmas Present for someone this year. A very collectible pattern.  There are two pages of extra pictures as we tried to show as much detail as we could for this rare outstanding set.
