CD 121 [010] W.F.G Co. Denver, Colo. 2 dot mold in a color that I would consider to be light cornflower blue. I've owned a regular cornflower blue but don't consider this to be dark enough to qualify but the shade of blue looks to be correct. Its possible this is one of those steel blue / Delft blue Denvers but I don't think so. I've placed it next to an aqua CD 110.5 for comparison since that is a pretty standard color most collectors are likely familiar with. There are some light bands of purple in the dome that show in a properly backlit display case. Its tough to see in the picture and I wouldn't consider this 2 tone but they are there. There is also an olive wisp that comes down above the CO in WFG CO and across horizontally. As far as Denvers go, the piece is in wonderful condition. Nice strong embossing on both sides and no annealing cracks. There is a W.F.G C ghosting across the front dome as well. Small pencil tip mark on dome, a razor thin small wire groove nick on the back and a small thin flat flake on the base. All of these are incoincidental in my opinion. $60.66 and that includes the shipping, even to Canada! The lucky emailer should be happy with this piece.
