This Troika Pottery Cube Vase is from my mother-in-law's home after we moved her to a adult care facility, independent living, now five minutes from us instead of 6 hours..  She is doing great at 91 years young.  I expect it was a gift from a friend that had traveled to England back in the 60's.  I believe she had some plants growing on her kitchen window sill.  Please see the images and ask questions.  It appears to be in very good shape.  The artist's initials look like AW for possible Annette Walters.  If you can tell me anything else about the piece, please do.  Thanks for looking.
