This candlestick holder was produced by the Jeannette Glass Company during the Depression Era, primarily in the 1930s and 1940s. The 'Iris and Herringbone' pattern, also known simply as 'Iris,' was one of Jeannette's most popular Depression glass patterns, featuring distinctive floral iris motifs and ribbed herringbone details. The iridescent marigold carnival glass finish was created by applying metallic salts to the glass surface before firing, producing the characteristic golden-orange shimmer.

Carnival glass pieces like this candlestick holder are highly sought after by Depression glass collectors and vintage home décor enthusiasts. The dual candle holder design with its elegant iris pattern appeals to collectors who appreciate American glassware history and the craftsmanship of mass-produced decorative items from the early 20th century. These pieces are valued for their nostalgic charm, beautiful iridescence, and their representation of an important period in American manufacturing when affordable glassware brought beauty into everyday homes during economically challenging times.
