Donate GNs to your local PBS auction. I ve done this several times. If you re a student, do a book report on one of the greats, like Maus, or on a title whose subject is appropriate to the class. Treat it with as much seriousness as you would a text-only book. If you re an art student, suggest a GN for analysis.
Comics are just as worthy of evaluation as any other art form.
If you re involved with a public art exhibit, such as a museum, suggest a display of comic art. This is a long shot, but sometimes you can catch people at the right moment. Make sure it s one that s readily available and appropriate for your particular group. If you think you can speak with some authority on GNs and you have a free university in your area, apply to teach a short overview class. This would be especially good for GN writers and artists.
