A couple of cute yellow goslings (Canada Geese) were part of the baby wildlife series issued in 2011
and for the Europa series in 2010 for Children's Literature, Lithuania issued a set of stamps featuring this boy on one side of the big book and a girl on the other (which I don't have)
and a Finnish Moomin from 2009
and from the young to the old, also from Finland, this one for the theme of mythical places with a bonus shaped stamp of geography (archipelago) both issued in 2008.
The natural rock cliff is in Southern Savo, in Ristiina on the shore of Lake Yövesi. A giant human face can be seen in the rock formations of the cliff and it has probably been some kind of cult site. Stone Age dwellings have been found nearby and it is thought that ancient residents considered the cliff a kind of god or an image of one.
