Vogue Paris Original Pattern 2043 - Balmain - Size 18

Vogue Paris Original Pattern 2043 - Balmain - Size 18 - UNCUT/Factory-Folded
This is a very special pattern, UN-Cut, UN-used  Size 18 - Bust 40"
I have not found this pattern available anywhere in this size, much less un-used, un-cut condition!  
This is pretty special to me, as my Mom had her dress made from this style for my wedding in 1972! See the 3rd photo. She is escorted by my late brother, Roger. 
"Semi-fitted A-line dress in evening or street length, has asymmetrical seaming and front wrap.  Side back zipper closing.  Front bateau neckline.  Bias now with buckle trim front and back."
