Initially, he devoted himself mainly to drawing, especially portraits, but he was mainly a landscape painter. His work is thematically focused on urban and rural nooks and landscape motifs. He is inspired by the Bohemian-Moravian Highlands and especially the surroundings of Jihlava.
The painting from the OGV collection is a typical example of Bláha's work in the 1950s, when he gradually abandoned realistic canvases and chose plain and simple themes to express his relationship to the landscape and the given motif.
