Original Nintendo Gameboy (Power and sound!)

Powers on, contrast slider works, screen works with decent view. Volume and speaker work. Couldn’t test 100% because I have no cartridges. Obviously the filter has become unglued but is in great shape. No battery cover. What you see is what you get. Will need a decent outer cleaning at least. Will ship as is so don’t damage anything trying to clean it myself. Will be shipped securely.
