In addition to landscapes, Ruberg created sentimental works that captured the mood felt by many in the Estonian exile community longing for their native land. In Omal Maal (1978) Ruberg depicts the skyline of Tallinn, the capital city of Estonia. The reverse side of Omal Maal (1978) shows Ruberg's inscription, taken from the Estonian folk epic Kalevipoeg, the last few verses of canto XVI, expressing the joy one feels when returning home after a long journey.
