Hobnail, Imperial
Five inches tall, these bells were produced in marigold (Rubigold), smoke (Peacock), amber, and pink. The IG mark is difficult to find; it's on the stem just below the finial (see inset). Most sell in the $15 to $25 range, pink a little less. Note the similarity of the compotes to the bells. The compotes are much more scarce than the bells and only listed in amber. The one shown above sold on eBay in 2003 for $25.
