Lot is for a beautiful antique sterling silver art nouveau style cigarette box case made in Mexico.  This one has a floral and fern design, and features a small Mayan calendar in the upper left corner front of the box.  The rear of the box has a diagonal panel for personal engraving (it is unmarked).  Spring hinged lid is in excellent working condition.  The hallmark on the bottom is in the form of a triangle, with the letters GUAD as the left leg (for Guadalajara), the letters MEX925 as the right leg, and ASG as the base, with a flame or flower symbol in the middle (see photos).  It is in excellent condition with some toning/patina associated with age.
