Alexander Yakovlev was one of the significant painters and graphic artists of the Russian art of the beginning of the 20th century. He was a representative of neo-academician style. In late 1900s he was interested in the impressionism. Yakovlev’s style and manner of painting were formed in early 1910s. Artworks by Yakovlev combined avant-garde and classic styles; he tried to imitate and to use methods of the Old Masters. He attached more importance to graphic art; his favorite technique was sanguine.

The Yakovlev’s art manner of painting is very similar to the V. I. Shukhaev’s one. Contemporaries called them the brothers-twins. There is a problem in determination and dating of Shukhaev’s and Yakovlev’s works.

Works by Alexander Yakovlev are in many museums of Russia and abroad, including the State Russian Museum, the State Tretyakov Gallery and the Pushkin State Museum of Fine Arts.
