They came from an estate sale in San Francisco in the late 1990’s. The product is a rare set of 36 3" mosaic glass tiles produced by Soule Steel Company in San Francisco during the 1960s. These tiles are antique original pieces featuring a multi-coloured mosaic pattern, made of glass and concrete materials. The tiles are reclaimed and showcase an antique style, making them a unique and sought-after addition for architectural and garden projects seeking a vintage touch. The company went out of business in 1985.
