RARE Harold Taub Vintage Cocktail Dress

This dress was made by designer Harold Taub in Montreal. I believe it was made for Madame Runge. Madame Runge was an upscale women’s fashion boutique that operated in Vancouver, BC from the 1930s until the late 60s. My guess is the dress is close to 65 years old. There is no size listed but I believe its approximately a size 10-12. It's condition is commensurate with its age. I have included pictures to give a sense of its condition. I found it with a bunch of items inherited from my grandmother. Similar items sell for $400+ online so you may be able to make a profit if you know how to sell to vintage collectors!
