Heavy Duty Teacups incised USA - The Star of the Road - Currier & Ives by Royal China. These are some of the scarcest items of Currier & Ives that I have run across. They are not mentioned in Aupperle's guide. What makes these items different is that they are 40% heavier in weight (ranges from 7.7 to 8.5 oz., average 8.1 oz.) than the regular teacups. They are slightly taller and much thicker. The base ring is slightly thicker and flater than the medium cups. The incised USA does not have any periods. The handle attachement is quite distinct in that it has an added flair at the bottom attaching point as seen on the left in the comparison image. If you click on the icon image on the left of this description you will get more images for comparision. It also has the letters USA on the bottom, but they are raised and not imprinted as is the usual method. These items are for the true collector! All items are sound, no chips, cracks or crazing unless otherwise noted. Buy with confidence from the largest supplier of Royal China Dinnerware. Quality is assured.
