Herr Eugen Duhring's Revolution in Science: Anti-Duhring (Classic Reprint)

They just went to marxists.org website, Anti-Duhring section, and pressed print and copy pasted all the webpages and glued them together and called it a book. No page numbers (despite the fact that the table of contents has page numbers so that's cool), font size is literally too small to read, page margin is huge for no reason, typo in the book cover. If you wanna scam people this hard, at least do a better job in making it not as obvious.
