In some old books I bought, I found an old postcard. It is dated Aug 15, 1935 from the Maher & Grosh Cutlery Co of Toledo, Ohio. It notified a customer that their order had been shipped and catalog #52 was being sent by separate mailing. It is very yellowed, but in perfect shape. If someone thinks this will help their collection (preferably someone who has a Maher & Grosh pocket knife) let me know. It is free.
