Fiestaware Teapot Set?

I am hoping that someone can help me identify this teapot set. It was my grandmothers, so I estimate she got it around the mid-fifties to early sixties. Each colored cup comes as a set of four. The blue wicker handled pot stands 8' from bottom to top of handle (4' not including handle) and the cups stand 2' tall and have a 3' diameter. I hope that the link that I provide will show the picture. Thank you in advance for your assistance. =)

The set is not Fiesta, or any other Homer Laughlin line. Due to the handle-less cups I'd 'guess' that it is something imported from China or Japan. Are there any markings on the bottom of any of the pieces?

unfortunately there are no markings on the cups or the teapot. That is what really has made this difficult for me. I appreciate your feedback, (and that's one less manufacturer I have to consider) and hopefully someone will know what this mystery set is. Thank you again!
