In the interwar period, Vaitys’ oeuvre was strongly influenced by Expressionism (this is reflected in the motifs and plastic expression). His landscapes are colourful and emotional: the artist was free in painting, aspired at harmonious colouring by joining the trees and meadows painted in fine vibrant brushstrokes into an artistic entirety which reflected the feelings raised by Lithuanian nature. The artist was interested in a dynamic condition of nature when winter was followed by spring, summer by autumn, etc., or in a transitional state of nature, e.g. before a storm or in rain. Jonas Vaitys in particular liked to reflect the feelings raised by nature in autumn: from the golden beauty of foliage when trees are dressed in colourful outfits until the last warm rays of sun in late autumn.
