Where Are the Pictures?

I was reading one of my many math books today and had a flashback to high school. At that time, I remember flipping through my dad's college math books and seeing no pictures. I was then glad to be taking calculus in 1999, and not some 30 years earlier. Thankfully I lived in modern times where there are full color pictures in every math book.

Now I'm trying to find a picture in my book. But really, who needs pictures?
