Ladislav Guderna, an artist inspired by Surrealism, Cubism and Fauvism, worked a lot with geometric shapes and their potential of painterly abstraction. Somewhere between his more realistic and the completely imaginary landscapes lies this jovial picture of the riverside (probably the River Váh). Objects and figures are neatly grouped and positioned as if to suit the almost flag-like distribution of vivid, complementary colors.
