Vintage matchbook cover, Souvenir of WHITE'S CITY at Entrance to Carlsbad Cavern National Park New Mexico, picturing the cavern entrance. Tiny number stamped on the inside. 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.
