It appears to me that it is a souvenier piece from Jamaica or Bahamas somewhere,, I have never seen one like it !! Even though it doesn`t have where its from on it,, could be that it had a cup or something that did !! Lots of people buy cup and saucer sets from their travels !! Neat little saucer though !! Even though our saucers are more shallow than that,, many places are not !!
