I love the sort of painting where you can see all the creatures that live in an ecosystem and imagine the complicated interrelationships between them.  This particular example is by long-time favorite wildlife artist, John D. Dawson, who was illustrating pull-outs for Ranger Rick when I was a youthful subscriber.  I had a large number of his web-of-life landscapes affixed to my bedroom walls.  They were stuck on with that peculiar blue tacky gum that gradually hardens until your poster falls off the wall.

I would still put this on my wall
