Vintage matchbook cover, CITIES SERVICE J. Leonard Johnson Warren Minn., picturing a can of Koolmotor oil. See scans for details on the condition. No matches. The black border is so all the edges can be seen and is not part of the matchbook cover itself. NOTE: All of the matchbook covers I have listed are guaranteed to be 100% authentic originals. All are clean and ready for display. Thank you for your purchase, I appreciate it.
