Pellon only makes non-woven interfacing and doesn't make woven canvas interfacing. I went to the Pellon web site, and their product list doesn't include anything with hair in it, so I don't know why this particular eBay seller says that this is a Pellon product.

I'd steer clear and order hair canvas from a reputable dealer, such B Black and Sons. The link is in the post that Sydnie refers to above.
