Last Tuesday I got a stamp set from Croatia on a postcard.
This is it:
Krapina Neanderthal Museum (issued 07-11-2012)
The Krapina Neanderthal Museum was opened in 2010 near the site in Krapina where the Neanderthals remains were discovered. It focuses on the prehistory and protohistory of the humanity and the Neanderthals of Krapina. It is considered to be one of the most interesting evolutionary museums in Europe.
Thank You very much Antonella!
