While the original source of this comic is dead, SauceNAO reveals that it has been reuploaded at several other locations, namely on DeviantArt. This one is a lower-res JPG, but has two comments (one from the original artist, one from another user) calling it out and linking back to the original source. This one seems to be an identical PNG to the source of the previous upload long ago (also dead), except for the "POKEMON COMICS.NET" watermark being absent and the original signature being present (also seen in the thumbnails of several other reuploads linked by SauceNAO (all of which are dead)). With this in mind, we can hopefully safely assume that this reupload is an identical file to what the original source was, or at least closer to it than the old source, being without the signature/date crop and third-party(?) watermark.
