Adam's Rib, Dugan
According to Carl O. Burns, in his 1999 book Dugan & Diamond Carnival Glass, Adam's Rib was introduced in 1925, bridging the gap between Carnival and Stretch Glass. The pattern is characterized by thin vertical ribs extending up from a squat pedestal base. There is a thin plain band around the pieces toward the top.

The pattern in found in mugs (like the celeste blue example shown here), lemonade pitchers, covered candy jars, compotes, fan vases, and several other shapes, mostly in ice green, celeste blue, but occasionally in marigold. A rare pattern.

The mug shown here sold on eBay in May, 2004, for $77. Another similar one sold in April, 2004, for $104. Photo courtesy of Jerry Franks.
