Buyer Confusion on Nancy Drew #10

I have stated how buyers can look at the spines of the Nancy Drew picture cover books to get an idea of whether the books have the original text. The picture covers with the original text tend to have the titles in mixed-case letters while the later books have the titles in all capital letters.

Here is another listing in which the buyer asked for more information about the books:

LOT OF 25 NANCY DREW MATTE PICTURE COVERS Item #110280366806

The buyer asked for a range of copyright dates in order to determine whether the books have the original or revised text. This is a good question; however, I wish to point out how a seller's pictures can reveal the answer without the buyer having to ask. The seller answered that the books were published from 1959 to 1971 and that all of them have 20 chapters, except for #24 from 1947. This seller's pictures are blurry, so it is very hard to discern what the titles on the spines look like; otherwise, we could tell for certain from just the spines whether the books are the revised text books. When the spines do not reveal the answer, the front cover illustrations will.

Refer to my Nancy Drew Picture Cover Gallery to view the cover art for the picture cover books.

With just a few exceptions, all of the Nancy Drew picture cover books that have the very last cover art, the art that is still in print to this day, have the revised 20 chapter text.

By knowing this piece of information, you can look at these blurry pictures from the above listing, see that all of them except for #24 have the final cover art, and tell that the books have the revised text:
