Night between July 30th and 31st

A guy I knew at University was giving joke presents to people. He had left me a small cardboard package for kid's colouring book and small set of colour pencils. Inside he had put lots of thick marker pens (mostly blue) and a thick pile of overhead transparencies that had either typewritten text or cartoons on them. The text was about some conspiracy theory, but I have forgotten details. Cartoons were all different. There was 6 or 8 panels per page and they were in simple line draw style similar to IKEA assembly instructions or airplane safety instructions.
