In 1998, Stoian Valkov emigrated to the United States. He took his first job at the Modern Art Foundry in New York as an artistic finisher. For five years he worked on the sculptures designed by other artists. Among them was french artist Louise Bourgeois. Stoian played a big part in the creation of giant spiders ”MAMAN” that this artist made in the last period of her work.
