Postcard

I've been experimenting with postcards, which are a unique challenge. They have to be able to go through the mail exposed without anything getting damaged or falling off.



This is done on a piece of a frozen pizza box. The lesson learned here is that the slick side of the pizza box does not hold paint well, and yet there is something about the box text and images showing through the paint that adds a subtle something.

I can't decide whether to stop here or keep going. I like the way it looks, and I'm afraid of ruining it, but it seems unfinished.

UPDATE:

I took Chris's advice.



Any other suggestions? See, I really do listen to your opinions.

There is also the question of what to do on the other side. I'm worried that anything I glue on will fall off. On the other hand, it looks pretty ugly.
