1917 ? Columbia Grafonola Colorized 10 x 13 Vintage Ad

This original 10 x 13" magazine ad I believe is from 1917, but am not   100% sure, as the page is not dated.  The ad is original and colorized to showcase the Columbia Grafonola Phonograph that plays Columbia and Victor records.  There is a tear along the left hand border that can be seen in the image.
