I'm not sure if you know, or care, but what you seem to be describing in your for-sale post are A16 and A17s that have been cut from their original pages. A web search for "Allen and Ginter" and "A16" or "A17" will provide you with more details. They do look like N28/29s with a blank back and thinner paper.
