This listing is for a vintage paper advertisement. This is a 1918 ad for a General Electric Mazda light bulb! The size of the ad is approximately 6x9inches. The caption for this ad is 'Scientific study coupled with practical manufacturing methods - this is the basis of the Mazda service that helps lamp-makers produce better lamps' The ad is in good overall condition, with some light wear. This vintage ad would look great framed and displayed! Add it to your collection today!
