Bogus tubes from WI WI tubes?

I would like to get your opinion on whether or not these particular tubes from WI WI tubes out of China are fakes or are the real deal. The tubes in question are the E88CC/6922 Amperex/USA @ $20.00 per tubes. Yeah $20/tube. Seems ridiculously low and given the reputation China has for cloned and forged goods, not saying all products from there, but most of you are aware of the reputation for less than par product. Here is the link. Hopefully someone can tell from the picture if they are indeed the real thing.
