I'm currently working on a chronology of Frank L. Fenton's work--from the decorations he likely did 1897-1904 for various employers to the designs for Fenton Art Glass Co. decorations and moulds 1905-1948. Thus, my use of the term "early" refers to his entire career, not just the Carnival glass era. In general, a Fenton line or novelty item makes its way into a Butler Brothers catalog several months after it was generally available. The exceptions are "exclusive" assortments just for Butler Brothers. I'll post when this project is complete ... probably near the end of 2006.
