Champagne connoisseur/detective needed

[writerbob]

Recently rec'd gift. Would like to know about it: value, quality, etc. Details---
-- From Label (near bottom of bottle):
TAITTINGER Collection
Champagne Brut 1982
Reims
Tiny # at bottom of label -- NM-162-001
-- From little label at bottom of BACK of bottle: Imported by Kobrand Corporation, NY
Sole United States Importers
But no luck on Net locating Kobrand in NY or elsewhere. (Since it's '82 vintage, co. could be long gone.)
-- Entire bottle covered by teal-colored plastic shell with what looks and feels like handpainted art. Most prominent is gold snow-covered mountain peak.
-- Below and to side of gold peak is black signature(approximately)"Andre Farson."
Rest of bottle has abstract flowers and what may be two flying figures in white with red hearts. Also some red lines on side and, below them in red, either a signature or undecipherable characters.
-- Pressed into plastic shell at neck of bottle is seal: knight on horseback with Latin words circling it. Just below looks like stylized version of gold sun or similar symbol.

Does this bottle ring a bell w/ anyone? It came from wine cellar @ Rio Hotel/Casino, claims to be best cellar in Vegas (tho' that's probably changed thanx to new Bellagio).
Would sure appreciate any info re this unusual package.

PS: Should this bottle be constantly refrigerated? I plan to pop it next New Years to help ring in Y2K.
