Hi, I was excited to find this in my backyard this evening in NW Indiana. I first thought it was a dog or cat tag but then was thinking aren't those usually issued by city or county? What's with the "corn states"? It's typical pet tag size, 1 1/4" high and 3/4" across the middle and aluminum. Back side is blank so didn't photograph. Found one similar on ebay but no details there on its origin. Any help appreciated!
