This is one of the few things on eBay I actually wanted to bid on and buy. When I was growing up Hinterland Who's Who "ads" would come on tv. The muskox, the loon, the grizzly and other animals found in Canada were profiled in these tv spots and the best part was you could send away for free brochures about the animals. We sent away for them a couple of times. You never knew what ones you would get and we read them many times. You can see many of the original ads on YouTube.
