I am very, very new to my interest in Carnival glass, so it's possible that I just haven't looked in the right place in my quest to identify this piece. I picked it up, unidentified, a few days ago, and while I've found similar patterns (Octagon being the closest), none of them seem quite right. There is no maker's mark that I've been able to find; there are a few smudges of opalescence on the base, but it was not covered in opalescence. I have looked through ddoty's site, as well as Warman's Carnival Glass book and the Standard Encyclopedia of Carnival Glass (10th Ed.) and my google fu has failed me. (It was not an expensive piece, so I won't be disappointed if it's new glass, a reproduction, or a fake. I mostly bought it because I liked it.)
Thank you for any help anyone is able to give me!
