Larios’ work is difficult to identify because it typically is not marked, his work was mostly sold through larger wholesale / retail arrangements with Main & Winchester or L.D. Stone.
The best way to attribute work to Larios is by confirming the pattern in a period catalog that attributes the design or workmanship to him with the assistance of a knowledgeable and respected dealer.
