The two variants that are listed are both entered as hardcovers, but they are regular comics. There are also at least 4 variants missing. I’ve provided a screenshot for you and I’m submitting 1F, which should be the Alex Ross variant.
Think you are looking in the wrong series. There is one without the HC in the title, the books you’re missing will be in there 
Thanks, I did find it after I looked again. There’s something I can’t quite figure out though. I have a copy of the Alex Ross foil variant which was included in the latest Alex Ross Collector’s Club box in October and it looks like it should match with issue 1G in the database, but the barcode on the copy I have shows as:
70985303999000111
You can see the barcode in the photo I posted. When I search on the barcode, nothing is returned by the database, so I’m not sure if the copy I have is yet another variant or not.
EDIT: It appears this is indeed exclusive, even though I see no physical difference from the foil variant listed as 1G. Check here:
I also see at least one eBay listing for $120 USD and they specify they are selling the copy that is limited to 1000 copies. What is your preference when a variant like this is missing? Do you want to add it yourself, or do you want me to just submit it as a missing issue using the normal submission process? Here is my suggested variant description for this:
Alex Ross Collector’s Club Exclusive Edition (Limited to 1000 Copies)
The barcode is the one I listed above.
