Not a flaw to be found anywhere. They must been brought back from Japan gone into a curio cabinet and not been touched for a hundred+ years until Fenton got ahold of them. They eventually made it to America from the UK. I love them but I prefer things a little further left from center for my personal collection so I'm moving them on. They are great size, not too small but also not too big that the average person can't fit them comfortably into their modern home.
They are unsigned, which is very common for Satsuma ware. The quality speaks for itself though, they were made in a good workshop. Just image the time it would have taken to painstakingly paint all this fine detail by hand.Many hours went into decorating each of these vases.
