I want! I want!

I found this picture on Twitter the other day. I had never seen it before but it turns out it is by William Blake. It is called "I want! I want!" and it's from his book for children "The Gates of Paradise". I looked at this picture and I thought that it might be about greed however I now think it is about someone wanting the moon so much - nothing is going to stop them getting it. It's a picture about finding away to solve problems and achieving a goal. Amazing wee drawing. Here's a link to the drawing http://simonthoumire.com/i-want-i-want/
