Very Rare unopened can of Active dry Yeast for Bakers. I searched everywhere for as much information on this can as I could. I could not find another full one like it let alone an empty one. This was manufactured by Standard Brands Inc. New York USA. (more info on the company provided below might give some insight to a possible date). The top of the can has the number 97080 this might be a clue as to the age as well. I apologize for not being able to give you anymore info then that.This would make a wonderful addition to a Tin Can Collection or even possibly a gift for that chef or baker who like unusual and rare things. Directions for use of this product is on the side although I would not recommend it for any kind of use in baking or consumption. It weighs 2lbs measures 7" tall and 4 1/2" across. The can is ribbed, color is blue with white and black writing. There is rust on the lid where the number is at but can still be read clear, also a few scratches but overall it is in great condition. Info: In 1929 the Fleischmann Company, the Royal Baking Powder Company, and Chase and Sanborn merged to become Standard Brands Incorporated. Later, in August of that year, the Canadian branches of the parent companies, including E.W. Gillett, officially became known as Standard Brands Limited.The origin of the Fleischmann Company dates to 1868 when two brothers who were bakers, Maximilian and Charles Fleischmann, joined with James M. Gaff, a well-known Cincinnati distiller, to form Gaff, Fleischmann & Company. The firm began manufacturing the first compressed yeast in the United States. The name was changed to Fleischmann & Company in 1905 after the death of James Gaff. The Royal Baking Company was created in 1863 by two druggists, Thomas Biddle and Joseph Hoagland, who developed the idea of mixing baking soda and cream of tartar in a premixed container so that homemakers did not need to do it themselves. Their product was called Royal Baking Powder and the business grew rapidly after its introduction. In 1873 the company was incorporated, and in 1899 the headquarters was moved to New York. The company introduced Royal gelatin desserts in 1925. In 1863 two Boston coffee and tea merchants, Caleb Chase and James Sanborn, combined their efforts to form a single company, Chase & Sanborn. In 1878 their company became the first to pack and ship roasted coffee in sealed cans. During the 1930s, the companies that comprised Standard Brands continue to introduce new products and new ways to market their goods, both in the United States and in new markets abroad. Fleischmann’s yeast was advertised on a nationwide radio program called “Bakers Broadcast.” In 1934 Chicago held a “Century of Progress” World’s Fair at which Fleichmann sponsored an exhibit for the baking industry. Fleischmann began selling products in Ecuador and the Philippines in 1935 and in Colombia in 1938. When the New York World’s Fair opened in 1939, Standard Brands had its own pavilion, displaying its largest exhibition ever. During the 1940s, Royal Baking introduced Royal Tapioca, and Fleischmann introduced its “Preferred” blended whiskey and bought the Davies County Distilling Company of Kentucky, a producer of bourbon. Standard bought the Standard Margarine Company of Indianapolis in 1942, adding to the company’s expanding list of products.
