GM Marketing was as productive in 1956 as it was any other year in the 50's. Supplying dealerships with both in house material and mailers to send out to "prospects"-- they had a number of campaigns through the Oct 1955 - Sept 1956 period to draw customers in. I've been collecting a wide variety of this "ephemera" for a number of years, and it's always exciting to come across a new piece that I don't have in my collection.
