So, consider this not-quite-hypothetical situation:
You--not really a teacher--are asked to teach what I'm going to, for the purposes of this post, call a high school art club. It's about a Drawing1 level.
After a bit, you realize these kids don't know ANY artists. They can recognize the names of really well known artists like Leonardo, Picasso, etc but not necessarily their work. When you ask them for examples of work they like/are inspired by, it's stuff from tumblr like doodles of dreamcatchers with pop lyric quotes.
What/who would you show them to get them started with a knowledge base?
Also, this hypothetical situation is in SEAsia (but not Singapore) so even though the kids like comic books and know Hellboy--for instance--it's from the movies and they have never seen the book as US comics are limited in availability and expensive. Same with art books, when they're findable at all. So even artists you might expect to be able to use as an access point, they aren't familiar with.
