1950’s Lenwile Ardalt Japan Teacups Signed V Ohado ?

There’s some really nice high quality artwork on a lot of the Ardalt Lenwile porcelain pieces.The artwork on these demitasse cups is exceptional.I thought these were transferware when I first seen them there that well done.Ive never seen any other Ardalt pieces that are signed like these are by a artist who’s name I can’t quite be sure of.It looks like V Ohado.Thanks for looking.
