First is 2-1/8” with 98% silvering but 2” line on the collet with surface oxidation. On the celluloid side this caused a thin brown line along the lower rim but most of it blends with the tinted scene which is titled “Manufacturers & Liberal Art Building.” Full gloss and displays nicely. Next is 2.75” oval. Three wide streaks of silvering gone but 80% remaining. Front names exposition and promotes “McCormick & Co./Baltimore, U.S.A.” with logo showing their “Bee Brand” trade mark and listing “Teas, Spices, Extracts, Drugs.” Gold side edges were probably once brighter but the only obvious age are a couple of near pinpoint grey marks on top edge. Overall VF. Last is 2.75” color tinted oval showing “Mines & Metallurgy Building.” Silvering about 90% intact and front top edge has .75” narrow and light tan mark. All are scarce.
