though there were other stores with their names on set boxes, Marx must have had a unique agreement with Allstate being the only brand name to appear on Marx rolling stock and even two highly prized Marx diesels. the Allstate E7 A-B-A set (#9638) w/ the orange Allstate bay window caboose may also be the most sought after 8-wheel deluxe plastic set though that is also based on some other rather unique cars in that rather large set (eg: orange Erie flat w/ green tractors, MP green stock car, etc).
many of these sets even packed Allstate labeled Marx transformers.
