Added information: the inspiration for this Fenton design is the "Scroll & Eye" plate made by Challinor Taylor in the 1880s-1890s. An original ad for C-T's "No. 100 10 in. plate" appears on p. 95 of Robert Lucas' excellent book on Tarentum PA glass. The Fenton plate is smaller, of course, and the design of the outermost edge is a little bit different, I think, probably in anticipation of how the piece would produce as pressed ware.
