"Shishkin is the folk artist. All his life he observed russian, particularly north forest, russian tree, russian thicket, russian depth. It is his kingdom and there he is unrivalled." said about Ivan Shishkin russian critic Stasov.
The most famous painting is "Morning in a Pine Forest" (one calls it with wrong name "three bears" although there are four bears). The painting was created by Savitsky who has painted the bears and by Shiskin who has painted the forest.
