Steffen, Lars, Klaus and I proudly present: our book on Spencer-Brown’s text “Design with the NOR”, which can be seen as the predecessor of his cult classic Laws of Form. To be released by Emerald soon, hopefully still within this year. Sharing the publisher’s three cover concepts with you, simply because I like all three of them. We have already decided which one it will be – feel free to give it a guess. (Photo of Spencer-Brown: Mirko Ludewig)
