Zack's Room Part 2

I got a cute new shelf for Zack's room and I am going to put one of these signs up for part of our zoo animal theme. I couldn't decide which one to use so I thought I'd ask what all of you think. I'm not sure if I like the all-black animals but I put it up anyway to see if you guys like it better. I posted a poll box to the right so please vote to help me decide! (The difference between the first 2, if you didn't notice, is only the wording "caution vs. beware".Sign #1 Sign #2 Sign #3
