1930 Kellogg's Kaffee Hag Coffee Let's you sleep Magazine Edge Ad

This original 3 x 11" magazine edge ad is untrimmed from it's original 8.5 x 11" magazine page.  It caught my eye because I never knew that Kellogg's offered a coffee product and the name is not one that sounds good, Kaffee Hag,  sounds more like a name for a clan of demons.
