This is ok. I probably got it as a trade in the mail in 1989. The "TREATSIE" [ie: TREATISE] at the beginning starts off w/:

"When you draw there is alot of math - adding subtracting, multiplying and dividing. The thought process is subtle."

Many of the images here appear to've originally been linoleum or wood cuts. There's a section of 4 drawings of cats that appear to represent 4 different mind-sets: ie: maybe each drawing was done under different stages of an acid trip. I don't know if the author did them or if they're from a psychology textbk or neither. There's one print of what may be a monkey holding a razor as if it's about to shave.
