The first bowl is someones representation of the Mayan or Aztec calender !! There are many variations as you can see above depending on who made it !! These were frequently souvenirs from Mexico !! The two brass bowls look like tourist pieces but no way to know where they came from unless its written on the bottom !!
The brass one with the lip design says India 40D on the bottom. The other one doesn’t have any ID or markings on it.
Do you happen to know the worth of any of it? I have alot of stuff with a lot of questions.
