Kirstein cough drops originated in Nuremberg, Germany in 1899 when pharmacist Dr. Carl Soldan combined eucalyptus and menthol to create a soothing lozenge for sore throats. Malted sugar cough drops were added to the company product line in 1932 and are still being produced today from the original recipe of boiling the malt sugar over an open fire and breaking them into chunks. Soldan's cough drops have been enjoyed by many generations and long considered to be a Bavarian treat, however I would argue that their glassine bags are the sweetest treat. These examples have no date, but could be as old as the 1930s when anthropomorphic advertising characters were routinely popularized for marketing purposes. Early in the 1930s, the Soldan company began printing their paper bags in their own print shop which was considered as an innovative move at that time. I presume they also had a small in-house art department of accomplished illustrators and lettering artists as well. Each of these glassine bags are currently available from this Viennese dealer. Below is an undated advertising postcard for Kirstein's cough drops from Vintage Postcards.
Below are two metal signs introduced in 1955. These Bavarian malt sugar characters are taking to the hills to promote the Kirstein cough drop family enterprise. The images were designed by Margit Sidonie-Doppler (born Kovaks), a student of Austrian-born designer, Joseph Binder. Via Genuin.
And here are two more BonBon bags from another Viennese sweet treat manufacturer also available here.
