Antique dome trunk

It's very sturdy seemingly made out of wood, and iron. It has a metal latch on the front to secure it closed. The inside of the dome has an old photo decoration on one side, it looks like there was one on the other side as well but its gone now. It has 4 very small wheels on the bottoms of it. I would love to know how old it might be or any information on it really. I cannot find any marks or stamps anywhere on, in, or underneath it.
