Awesome ad. I faintly remember this stuff. Never used it, but it's a great example of the kind of advertising we were subjected to in the 70's, along with disco.
Oh boy. Look out now. eBay prices for this "rare" classic will now go off the scale of reality. Doesn't everyone know what a classic this is? It is why it has so many reviews here. Seriously, you have to give it up for some of that packaging from back in the day.
