In 2020, Slovak professional theater celebrates the one hundredth anniversary of its founding, and in commemoration of this occasion the Slovak National Gallery prepared an exhibition of professor Ladislav Vychodil(1920-2005), for whom this year marks the one hundredth anniversary of his birth.

The project refers to a term established by Karol Vaculík and curators of the national gallery in the early 1960s through the large exhibition Generation 1909 - Conscience of the Epoch (1964). The title reflected the "arithmetic" average of the birth dates of the particular authors selected for the group by the curator. Their affiliation to the group was not only biographical; the curators tried to find also other common features and connections.
