1914 National Mazda - Edison Light Bulbs - Original Ad #1864

This original 11 x 14" magazine ad was published in 1918 to promote the National Mazda Light Bulb by General Electric, also known as the Edison Light bulb.  The ad does have an edge flaw from long ago down near the lower right hand side of the image, however it just adds to the character of this antique ad IMO.
