Wall paintings and oil paintings were made by John A. Mallin (1884-1973), an artist of Czech origin, and his company. We don’t know the exact date when works of Mallin were created, but we know that the original appearance of the painting decoration differed from the contemporary one, but also from the one that we know from the photographs taken in the 1940s and 1950s. It is known that the artist worked in the church again twice in the 1940s.
