Inside the family-run Petosa accordion shop which has been in business for 100 years. Basically it's a collection of over 100 different accordions, some more than a hundred years old, reverently displayed in a building where the Petosa family makes and sells accordions. See the 1907 piano accordion, the rare Uniform Keyboard accordion, the first accordion made by Carl Petosa in 1922.
Originally located in the Wallingford district of Seattle, Petosa relocated to Lynnwood where they report they are able to display many more accordions, but still only about half of their collection.
