No Clue=please help

This is 5"x3"x3". I don't know what it is made of-terracotta is my best guess. I wonder if it is very old or a recent attempt at appearing that way. The black spots on the bottom are holes. It seems like a miniature sarcophagus. Gotta satisfy my curiosity-haha!
It does have rather large chips.

The chip on the front suggests it's not terracotta, maybe soapstone?
The design round the lid is "Greek key", so maybe a clue.
A few more pics may help, eg the inside, and underside of the lid.
Those lines on the bottom are suspicious, possibly from machining?

My first guess would be tourist ware of some form or another. The raised pieces look like timeless generic images of Greek/Roman figures which are probably applique moulded plaster. It looks like the surface is uncovered on one corner, and looks white. That is not a terra-cotta colour.

The bubbles indicate it’s made from an alabaster-effect resin, copying an Ancient Greek or Roman artifact. Probably made for sale in museums and to tourists.
