"Wire Spiral" Refreshment Set. The plate is 6-1/8 inches in dia. and the tumbler is 3 inches tall.
This set is not documented in amber nor as #3103, but a spiral optic pattern #3103 was made in emerald, rose, and blue by Fry. This set is shown in rose in the Fry Glassware Collectors book, p.99, which is why it is listed in this section of the Gallery.
Fry did make amber glass, but it is possible this set was made from Co-Operative Flint molds by Phoenix Glass as their #6357 cocktail plate.
