Dec. 56 = Dodge News has moved on to the 1957s. Thumbnails of the front and rear covers are shown below for verification. The center two page spread is an advert for the "1957 Swept Wing Dodge Unleashes a Hurricane of Power". Features the new Torqueflite "1-2 Punch" as an inset.
I got this as part of a package of 5 issues of Dodge News - the other four related to the 1956 Dodge, so those are keepers. I am willing to give this away for the price of postage, probably $5.
