Absolutely brilliant blues, this Gefle porcelain tea cup and saucer set was designed by noted Swede Berit Ternell.  Produced only 1970-1975, this pattern is Bla Blomsten- "blue flowers" and labeled F555.  The mid century modern designs are experiencing a strong revival. No chips, cracks, repairs or crazing.  Former owner was a world traveler and only proudly displayed her collection. Measures cup 2 1/2" tall x 3 1/2" diam.  Matching saucer is 6" diam.
