In 1937, the Museum Board initiated the publication of stamps with the portrait of the physiologist Johann Evangelista Purkyně. Stamps after the relief by Otakar Španiel, designed by Bohumil Heinz, were printed in two colors and two denominations by the Unie print works in Prague on September 2, 1937. They were valid until the end of 1937. NML Medical Museum, MGZ 46
