Very Rare 1940s Simplicity Designer Sewing Pattern 8056 V Neck Dress Sz 18 UNCUT For Sale

This is a vintage sewing pattern from 1949 by Simplicity. The pattern is for an evening dress with a V-neckline. It is a very rare find and has not been used or cut, making it an unaltered original. The dress is designed for women and comes in size 18.  

This is an 8x10 oversized pattern envelope, similar to the Vogue Designer Series.  I have not been able to find even one reference to or sale of this pattern online.  As a pattern seller, this is quite unusual and makes it a true collectible.  

The envelope is in very good condition relative to its age.  There is some toning and edge wear but nothing significant.
