German Perpetual Calendar Preowned in good condition Wooden Sliding Painted Folk Art Wall Calendar Measures: 17” long x 7” tall Google Translate: To hang the calendar, you will need two nails with a head diameter of approximately 45 mm and a length of 20-30 mm (steel nails). The nails are hammered vertically one above the other at a distance of approximately 13 cm (the width of the back panel is 13 cm) deep enough to leave 4-5 mm between the wall and the head (the thickness of the calendar back panel). Then, hang the hole at the top of the upper nail and snap the lower slot into the lower nail.
