Vintage Black Market Rabbit Fur (Outside) Polyamide (Inside) Women's Bucket Hat

The hat was made in Canada by a company named Black Market. I tried to do some research on the compnay, but it must be out of business. No information was found. You can tell by the tags that it is vintage, I'm just not sure of the exact time frame (60's, 70's, 80's). It is Poil De Lapin (Rabbit Fur) and Polyamide inside. See picture four. I'm not sure if the band is stretched or if it was made this way. There is no size listed, but it fits me perfectly, and I wear a size large.
