Yellow Pitcher and Glasses Set - Import?

Hello Board Buddies! I've got a yellow juice or lemonade set that's got me stumped. The pitcher stands 7 1/4" tall and each glass is just a shade under 3" tall. The pattern is a reverse thumbprint. The bottom has a rayed pattern. The glasses are a bit inconsistent. On some the thumbprints are well defined but on others the pattern is washed out. And on some the rayed base is dead center but on others it's quite a bit off-center. I've black light tested it and it is not vaseline - it glows purple instead. Does anyone recognize it? As always, thanks very much for whatever information you can provide.
