Vintage postcard, HOUSTON OILERS, with the older NFL helmet pictured, unused. See pictures for details on the condition. Size is 4" x 6". The black border is so all the edges can be seen and is not part of the postcard itself. NOTE: All of the postcards I have listed are guaranteed to be 100% authentic originals. They are all clean and ready for display. Thank you for your purchase, I appreciate it.
