I bought this at an antique shop a few years ago and now wanted to see when it was in use the 1910s was a guess and if it had any value

I have a Basilosaurus (Whale) lumbar vertebrae that was found in my great grandparents land/creek when my father was a child. My great grandparents found this vertebra in a creek located in Mississippi. I don't know much about it other than what I can remember my grandmother telling me from when I was a child. Size is around 12.5x8.5in

Found this at a estate sale not sure if it’s a drawing or photograph looked very old would like to know more about it

This cash register was found in the basement of a house in Atlanta that was built in the 1920s. It has a lot of wear. The pop-open drawer is still functional.

From the 1970s
