M.I. Hummel porcelain figurines are only one adaptation of Sister Hummel's art. Other collectible adaptations are Hummel dolls, plates, prints, pictures, postcards, calendars, books, bells, boxes, and candles.
M.I. Hummel dolls are made exclusively by the W. Goebel Company and were added to the line in 1955. W. Goebel had been making other dolls since 1871. These dolls are made with vinyl plastic. Doll collectors report that these dolls can be bought in the United States, but can be purchased for considerably less in Germany, where is seems the majority of Hummel dolls are sold.
M.I. Hummel plates entered the Goebel line in 1971 with their first limited edition annual (Christmas) plate. That same year, Schmid Brothers, Inc., of Randolph, Massachusetts, introduced a Berta Hummel Christmas plate. Since that year both companies have continued to produce commemorating plates plus at least one limited edition each year. Schmid also introduced a limited edition Mother's Day plate in 1972 and has issued one each year since.
Paper prints, pictures, and postcards adapted from Sister Hummel's original paintings actually predate the production of figurines. Josef Muller and Emil Fink, both publishers, entered into separate agreements with Sister Hummel and her convent for the rights to reproduce her works in the early thirties. Paper calendars based on Hummel are are made by W. Goebel, Emil Fink, and Josef Muller.
Three books reproducing drawings and paintings of Sister Hummel are The Hummel Book, by Hummel and Seemann, copyrighted by Emil Fink Company in 1934, The Hummel published and copyrighted by Josef Muller in 1939, and a rare, out-of-print biography by and American Franciscan nun entitled Sketch Me, publisher and date unknown.
Hummel bells, boxes, and candles for the most part are distributed by the Schmid Company using transfers or decoupages of reproductions of Sister Hummel's art. These adaptations can be identified in the same way as the reproduced Hummel Prints, by the signature of Sister Hummel found in many forms. If the picture has been cropped, the collector must learn to recognize genuine Hummel adaptations, look for the Schmid name, or trust his dealer.
There are many Hummel-like products on the market of every type and form imaginable. The principal, authorized adaptations of Sister Hummel's can be identified by checking for the facsimile signature, the company, or by learning to recognize the distinctive style of Sister Hummel's art.
