Vintage document, LEON E. BLOCH Principal Note Kansas City Mo., early one, in n-mint+ unused new old stock condition. Nice clean document. Size is 4" by 10 1/4". Scans show the front, back is blank. The black background is so all the edges can be seen and is not part of the document itself. NOTE: All of the advertising items 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.
