The Old Turnstyle - Windmill:  A turnstile, also called a baffle gate or turnstyle, is a form of gate which allows one person to pass at a time. It can also be made so as to enforce one-way traffic of people, and in addition, it can restrict passage only to people who insert a coin, a ticket, a pass, or token.  This picturesque greeting card features both the turnstile and the windmill to which it allows access.  This Divided Back Era (1907-15) card is in good condition.   No. 1802.
