Vintage note sheet, GRINNELL COMPANY Plumbing and Industrial Supplies Fire Protection Systems No. Kansas City MO., in n-mint unused new old stock condition. Couple of mild wrinkles from storage. Size is 5 3/8" x 8 1/4". The black border is so all the edges can be seen and is not part of the note sheet itself. NOTE: All of the advertising note sheets I have listed are guaranteed to be 100% authentic originals. They are all clean, unused and new old stock unless otherwise noted. Thank you for your purchase, I appreciate it.
