HUH!? I had NO IDEA "Northwest Rock Trading Cards" existed! Why y'all wanna keep such a sweet secret from me, Northwest Rock?!

It appears these were used as promo adverts for the shops where you could pick 'em up. Um, I know it's been over two decades, but does anyone remember if this was via the Rocket or Hype, perhaps? Does anyone have these? Anyone with a complete run?! I'm impressed both Accused AND Gruntruck got a card!
