This lamp is shown in a catalog reprint in the back of "Fenton Art Glass 1907-1939' by Margaret and Kenn Whitmyer. The ad is noted to be circa 1931-1932, and the Daisy decoration is listed as 'Dec. 9'. These lamps are sometimes called 'pancake lamps' because of the base.
These lamps are often confused with a similar style made by Jefferson Glass.
