YIJ trading cards question

I just picked up a set of the Young Indiana Jones trading cards on ebay... it was listed as complete.. but I found a website that states that in the series there are 8 of the hidden treasures cards.. my set has six.. however the site does not list the card titles.. I have : German East Africa, Peking, Verdun, Mexico, Egypt, and Congo..... what am I missing ??
THANKS !

Here's a scan of the back of the official list given out by ProSet...



Hope that is of some help...

I had to buy two full boxes to get the whole set of them. I don't remember which ones were hard to find though. I'm guessing someone had a ton of a couple and thought they were all there.
