During the vintage period, HLC produced limited versions of striped Fiesta products. They came in three colors of stripes: red, blue, and green, and on two base colors: ivory and yellow. Red and ivory are the most common of these rare combinations, and the most popular, due to the fact that they look the best together.
All stripes are hand-painted. Green was likely a Sears exclusive.
Recently, the striped look has been reintroduced, so make sure you aren’t paying vintage prices for a post86 piece!
