This listing is for a vintage oversized matchbook with advertising for Scientific Supply Company Inc., JA-DA, of Denver and Glendale, Colorado.  It shows some signs of wear, and the staple at the bottom no longer holds the bottom cover.  Condition as shown in photos.  

Please let me know if you have any questions.

I will combine shipping when it is reasonably possible.
