In many places in the early days of automotive transportation, low-quality fuel caused carbon build-up in a vehicle’s engine. “Carbon-X-It” was the solution to carbon build-up, and this paper poster ad let all drivers know! The ad has been professionally matted and framed and features two drivers on the road. One is broken down with a carbon issue, while the other zooms by, enjoying their day. It is in fantastic condition and dates from the 1920s. In the upper left corner, some minor staining is evident. This ad is a genuinely exceptional piece seldom seen in this condition. 21171-TWP
