Words and letters are like colorful and voluminous forms in the works of Mahmoud Zindaroodi on different substrates turned into calligraphies. Mahmoud Zindaroudi should be recognized by his focus on volume and geometry and variety of work with different materials rather than being attributed to the school of Saqaqhana and calligraphy. Zindarudi entered this profession years after his brother Hossein Zindarudi; But he took another path with his influence. Mahmoud Zindaroudi's works have been in the auction 21 times and so far a large part of his works have been sold and are on an upward trajectory until 2022. In this conversation, Zindarroudi emphasizes his artistic path and the beginning of Saqaqhana by his brother, and considers the quotes attributed to the beginning of this school by other artists to be wrong.
