or at least help me figure out what to type into my computers search engine, I found it in my backyard last summer, someone on the general forums said it was from the 1893 chicago world's fair, I have no idea what it is though, it looks like it may have been a lid to something. You can see by photos 3&4 whatever it was you could lift the lid and slide the bottom part out to make it wider, the top part with the photos is in 2 halfs that you can seperate, the last photo shows the size.
