This is a known model no 3544 Weiss, Kühnert & Company, Gräfenthal, Thuringia, porcelain glazed right-facing woman's side-buttoned cap toe shoe with in-mold pairs of geese and an in-mold gosling on the outside rear quarter.  It is fully glazed.  It is known to be made also as a left facing shoe. Glaze coat is clear with gilding of rim, laces, and toe cap boundary. One goose sits on the vamp; one strides the right vamp.  Geese are white & black with brown-red bills and feet. Toe cap is pearlized pinkish gray, which is aged from the original more minty green at manufacture.  Book value is $150 for this impressive large size, but I am discounting it because of the color change, which is only an issue if you plan to display it next to a mintier shaded left-facing shoe.   No chips or fractures, and gild is perfectly intact. "Germany 3544" is impressed on the left side of the heel.  See page 168L3.2, Wojtkowski , Porcelain and Pottery Shoes, Schiffer Pub. 2004.  Shoe is probably 1920s vintage, but could be earlier. Shoe size is 6-1/2 x 2-3/4; 7.6 oz.   Item #1228, Price $45.
