Nippon lemonade set w/ desert plate

NIPPON hand painted lemonade pitcher with Five mugs and a desert plate. This pattern has African Violets that are so vibrant! Marked with the TE-OH mark im placing it early 1900's. This is quite a set. The only weird mark on pitcher is in pic #7. It was obviously done after painting because its smooth to the touch. So it was fired that way. Also, one of the cups has a, what looks like a bubble that pooped while firing. Both marks im thinking were there when first sold...
