Hi. I came across this piece and was wondering how common/rare it is. It is a porcelain piece in a nice multi-tone brown/tan. Since I am a glass collector, I would label this as a CD 145. On the dome is 'N.A.T.CO.' stamped in an arc. I know this embossing from the CD 151 Peacock pieces. Anyone else out there have one like this? I have posted a second photo of a side shot. Thanks for the help.
