Karan Reshad (*1981) aka A1one aka Tanha, is an Iranian visual artist who pioneered graffiti and street art in Iran. His career as an artist began in his hometown, Tehran. He was the first person who started painting on walls of Tehran so his nickname ended up being "Alone" which then mutated into A1one. He started his street art project in 2003 and inspired his close friends at that time to also begin painting on the streets. Artists such as Elle, Isba, K.T. and Magoi were the first people to join him in Tehran. He is one of the pioneers of the urban art scene in the Middle East.
