Number of arachnid related stamps in issue: 1/5
This series is a little far fetched. I have included it because among the figures shown, there is an arachnologist that contributed several articles on opiliones, solifugids and spiders, Dr. Eduardo Ladislao Holmberg born in Buenos Aires on June 26, 1852.
