I couldn't figure out what the circle one on the left was until I stamped it. Then I recognized "It's an eyeball!"
The same thing happened with me and my Bullet Bill stamp earlier: when I took it out of the package, I was holding it at a 90 degree tilt, and could not figure it out for the life of me. But as soon as I stamped it, I could see which way to turn it -- and the likeness was so perfect, I couldn't believe I had missed it at first!
There's a tiny dent in the rubber (from shipping, probably) on the cuff, which is located just right to read as a button!
It absolutely does read as a button, I would never be able to tell from the photo that it was a dent. As far as I'm concerned, it was intentional!
