I’m looking from where this picture is from it was taken in 2007 of my grandad who recently passed away and I’m looking to visit this shop https://i.redd.it/rbu8n5nk28qd1.jpeg Posted by Patient-Run3812
Does anyone know much about the this book? Where it was printed and what it was used for? There are several editions with different years at the bottom, aside from that they seem mostly the same, the contents are math formulas.
