This gallery at https://e-hentai.org/g/21932/8a794af44c/ seems to have an incorrect cover image added to the gallery https://e-hentai.org/g/27388/78965fa169/ . Perhaps a person made a false version of this scan by adding an image that is like the cover of this first edition with the name of the first edition, it was , in truth, an addition of one image to a previously existing gallery with a false name.
Nonetheless, good eye for details.
