This offering is for a Fenton Blue Ridge-Cobalt Edge French Opalescent 4" swirl vase #2625 manufactured in 1985 for the Fenton Company's 80th Anniversary.
This pretty little vase is pristine. I see no damage of any kind. The mark is acid etched on the bottom, FENTON over 80th and has the small Fenton oval with an 8 and the mark is pictured.
This item is one of ten Blue Ridge pieces that were issued to celebrate the 80th Anniversary of the Fenton Company. They originally produced the Blue Ridge pieces in 1938 but these ten items made in 1985 are all different from the original production items and they are all marked with the 80th mark and the Fenton oval 8 logo.
This item is pictured on page 146 in the book "Fenton Glass Compendium-1970-1985" by John Walk.
Great item for your collection.
