Butter dish. It has a mark that is partially worn off; all I can make out is A Rogers. It might be silverplate, not sure. It has a very nice glass insert and is great to use for everyday or special ocasion meals. It is 8 long x 4.5 wide. It appears very dark in the photos, but it is not. It is pretty shiny but needs a little polishing to make it even brighter. 1/24
