Mandalian manufacturing co. was located in North Attleboro Massachusetts. ( I live close to this area) was founded in 1915, but its origins go back to the early 1900s. That's when Sahatiel G. Mandalian (1869-1949), a Turkish immigrant, formed a partnership to make jewelry and novelties. 1906, he and Eugene A. Hawkins began manufacturing mesh purses to compete with Whiting & Davis. When his partnership with Hawkins ended in 1915, Mandalian incorporated under his own name. The mesh had furnace-fired enameled links that glowed, and the company advertised the product as "pearlized mesh." Mandalian purses are eagerly sought by collectors and I have seen them sell for $200 to $595, depending on style, frame and condition. The company was sold to Whiting & Davis in 1944. Whiting & Davis is still in business in Attleboro Falls, Mass.
As far as pattern I will have to break out the collectors books and try to hunt it down. I also have several bags made by them beautiful craftsmanship. Good find!!!
