The dish has a Ring pattern that closely resembles Hocking Ring and is considered a "go-with". Several Forum members suggested this is Fenton due to foot shape and crimped rim. No documentation for either Hocking or Fenton has yet been found. The Black Glass Encyclopedia, p.32 by West Virginia Museum of American Glass, shows this piece as unattributed and points out "similar to Fenton's [#100] Wide Rib viewed from top, but very different from this angle [side view of underside showing 2 bands of rings and different contours.]"
