In 1976 Wirkkala was invited to participate in an exhibition of masters of art glass in connection with the Venice Biennial.

An interesting work of environmental art was a monument to President Kekkonen on Saivaara Fell, which Wirkkala designed in 1978. It consisted of an unobtrusive path marked with natural stones running east-west parallel to the crest of the fell.

In 1970, Rosenthal's Century centennial dinner service was completed, having been several years in preparation.
