Since 1921, the diagnosis of type 1 diabetes no longer means a death sentence. The reason for this is the invention of insulin. This groundbreaking discovery is on a par with the antibiotic. The three-dimensional model visualized on the stamp shows the tertiary structure of an insulin molecule and at the same time resembles a garland. Because: there is something to celebrate. Happy Birthday Insulin.
For the typography, we used our own Diglû, a font with pictograms.
