Item is a cardboard box, still sealed. The insulin is from Lot #73850 B1585, according to the label on the bottom of the box. The label on the front of the box reads: '5cc ampoule Iletin Insulin Lilly for clinical test. Approximately 20 units in each cc. Eli Lilly & Co., Indianapolis, U.S.A.' Stamped in black on box top: 20 new U units. This insulin must have been produced after April 1923 when Lilly agreed to modify the name of their product by adding the words 'Insulin, Lilly' to the product labelling.
