Janeček's entire oeuvre of poetic expression with a significant role of color is thematically focused on nature and its detail. Ota Janeček's works can be found in NG in Prague, Tate Gallery and other collections around the world. Still life with fish belongs to harmonious works, where the author uses the area to the maximum and complements it with earthy color. We can also see similar fish in the author's graphics. Attached confirmation of authenticity from Ing. Tomáš Janeček.
