This flipnote has been restored from corrupted data.
The archive managed to come in possession of about 400 or so flipnotes that were extracted from Hatena Servers immediately after the site shut down. Viewing them in the flipnote menu reveals there is data contained in them, however, the data is most likely corrupted.
Usually we would consider this corrupted data a lost cause if it wasn't for one flipnote that has all its data intact. It raises a more questions than it answers, and it brings into question the authenticity of the other ppm files in the collection, as well as their upload date.
