Original Quick mit Lezithin "heart refreshing, nerve strengthening" tablet tin. Provides strength for professional and sports performance. Energy supplements have been very popular in Germany for a long time and frequently found their way to the front for obvious reasons. I have seen this exact tin ground dug from battle fields in Russia. The price on the back of the tin is listed in Reichsmarks. The tin is in good condition with some light wear.
